Underlying Event measurements in pp collisions at root s=0.9 and 7 TeV with the ALICE experiment at the LHC

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p(T) thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2-3 between the lower and higher collision energies, depending on the track p(T) threshold considered. Data are compared to PYTHIA 6.4, PYTHIA 8.1 and PHOJET. On average, all models considered underestimate the multiplicity and summed p(T) in the Transverse region by about 10-30%.7Calouste Gulbenkian Foundation from LisbonSwiss Fonds Kidagan, ArmeniaConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Financiadora de Estudos e Projetos (FINEP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)National Natural Science Foundation of China (NSFC)Chinese Ministry of Education (CMOE)Ministry of Science and Technology of China (MSTC)Ministry of Education and Youth of the Czech RepublicDanish Natural Science Research CouncilCarlsberg FoundationDanish National Research FoundationEuropean Research Council under European CommunityHelsinki Institute of PhysicsAcademy of FinlandFrench CNRS-IN2P3Region Pays de LoireRegion AlsaceRegion AuvergneCEA, FranceGerman BMBFHelmholtz AssociationGeneral Secretariat for Research and Technology, Ministry of Development, GreeceHungarian OTKANational Office for Research and Technology (NKTH)Department of Atomic EnergyDepartment of Science and Technology of the Government of IndiaIstituto Nazionale di Fisica Nucleare (INFN) of ItalyMEXT, JapanJoint Institute for Nuclear Research, DubnaNational Research Foundation of Korea (NRF)CONACYTDGAPA, MexicoALFA-ECHELEN Program (High-Energy physics Latin-American-European Network)Stichting voor Fundamenteel Onderzoek der Materie (FOM)Nederlandse Organisatie voor Wetenschappelijk Onderzoek (NWO), NetherlandsResearch Council of Norway (NFR)Polish Ministry of Science and Higher EducationNational Authority for Scientific Research - NASR (Autoritatea Nationala pentru Cercetare Stiintifica - ANCS)Federal Agency of Science of the Ministry of Education and Science of Russian FederationInternational Science and Technology Center, Russian Academy of SciencesRussian Federal Agency of Atomic EnergyRussian Federal Agency for Science and InnovationsCERN-INTASMinistry of Education of SlovakiaDepartment of Science and Technology, South AfricaCIEMATEELAMinisterio de Educacion y Ciencia of SpainXunta de Galicia (Conselleria de Educacion)CEADENCubaenergia, CubaIAEA (International Atomic Energy Agency)Swedish Reseach Council (VR)Knut & Alice Wallenberg Foundation (KAW)Ukraine Ministry of Education and ScienceUnited Kingdom Science and Technology Facilities Council (STFC)The United States Department of EnergyUnited States National Science FoundationState of TexasState of OhioFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Underlying Event measurements in pp collisions at s=0.9 \sqrt {s} = 0.9 and 7 TeV with the ALICE experiment at the LHC

We present measurements of Underlying Event observables in pp collisions at s√=0.9 and 7TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p T,LT in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p T thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2–3 between the lower and higher collision energies, depending on the track p T threshold considered. Data are compared to Pythia 6.4, Pythia 8.1 and Phojet. On average, all models considered underestimate the multiplicity and summed p T in the Transverse region by about 10–30%

This study aimed to investigate the clinical/biochemical course of kidney transplant patients and its relationship with personality traits in the 3rd, 6th and 9th month after transplantation. Participants were 114 kidney transplant patients, 68 men and 46 women, with an average age of 47.72 years (SD=11.4). Personality was assessed using the Brazilian Factorial Personality Inventory (BFP). Patient charts were used to record clinical/biochemical variables over nine months following transplantation (hypertension, acute rejection, graft loss, death, creatinine and estimated glomerular filtration rate/eGFR). In addition to sociodemographic variables, information was also collected on transfusions prior to transplantation and panel reactive antibodies (HLA I and II).Two groups with personality types were differentiated by psychological characteristics (hierarchical cluster analysis): Cluster 1- average Neuroticism, high Surgency, Agreeableness and Conscientiousness, and low Openness; Cluster 2- high Neuroticism, average Surgency and Agreeableness, average Conscientiousness and low Openness. There was no statistically significant difference between the two clusters in terms of hypertension, acute infection, graft loss, death and HLA I and II panel reactive antibodies. Creatinine levels, eGFR and transfusions were associated with personality types. Cluster 1 contained significantly higher creatinine levels than Cluster 2 and these remained high on all three assessment occasions, with transfusion prior to transplantation less frequent in this group. Cluster 1 exhibited a slight decrease in average eGFR over time, with an increase observed in cluster 2. In individual analyses, Neuroticism was higher in patients with lower schooling levels (p=0.002) and exhibited a significant positive correlation with average eGFR (r=0.250; p=0.008). Agreeableness was significantly higher in men patients (p<0.001) and those without infection (p=0.050). Agreeableness also showed a significant positive correlation with average creatinine levels (r= 0.250; p= 0.007) and a negative association with eGFR (r=-0.208; p=0.027). Higher levels of Conscientiousness were observed in participants with children (p=0.026) not taking medication for depression (p=0.033), as well as a positive correlation with HLA I panel reactive antibodies (r=0.223; p=0.018). In relation to Openness, the only statistically significant difference identified was in relation to schooling, with higher average values found among participants who had completed higher education (p=0.037). The results suggest that personality traits may be associated with transplant results. Monitoring these patients over a longer period may provide a better understanding of the relationship between personality traits and clinical course during the posttransplant period.A rela??o entre personalidade e sa?de tem sido objeto de estudo frequente em pesquisas cient?ficas. Este estudo teve como objetivo principal investigar a evolu??o cl?nica/laboratorial de pacientes transplantados de rim e sua rela??o com tra?os de personalidade no 30, 60 e 90 m?s ap?s o transplante. Participaram do estudo 114 pacientes transplantados renais, 68 homens e 46 mulheres, com idade m?dia de 47,72 anos (DP=11,4). Para a avalia??o da personalidade foi utilizada a Bateria Fatorial de Personalidade (BFP). A partir dos prontu?rios, foram registradas as vari?veis cl?nicas/laboratoriais ao longo de nove meses ap?s o transplante (hipertens?o arterial (HA), rejei??o aguda, infec??o, perda do enxerto, ?bito, creatinina e taxa de filtra??o glomerular estimada/ TFGe). Al?m das vari?veis sociodemogr?ficas, coletaram-se ainda informa??es sobre as transfus?es pr?vias ao transplante e Painel de ant?genos HLA (classe I e II). Dois grupos com perfis de personalidade foram diferenciados pelas caracter?sticas psicol?gicas (an?lise de cluster hierarquizado): Cluster 1- Neuroticismo m?dio, Extrovers?o, Socializa??o e Realiza??o altos e Abertura baixo; Cluster 2- Neuroticismo alto, Extrovers?o, Socializa??o, Realiza??o m?dio e Abertura baixo. Para HA, rejei??o aguda, infec??o, perda do enxerto, ?bito e Painel de ant?genos HLA, classe I e II n?o houve diferen?a estatisticamente significativa entre os dois Clusters. Os n?veis de creatinina, TFGe e transfus?es tiveram associa??o com os perfis de personalidade. Verificou-se que o Cluster 1 concentrou n?veis de creatinina significativamente mais altos que o Cluster 2 e que se mantiveram mais elevados nos tr?s momentos de avalia??o, sendo a transfus?o pr?via ao transplante menos frequente neste grupo. No Cluster 1 ocorreu leve redu??o da m?dia de TFGe ao longo do tempo, enquanto que no Cluster 2 houve aumento. Nas an?lises individuais, Neuroticismo apresentou m?dias mais elevadas nos pacientes com menor escolaridade (p=0,002) e correla??o significativa e positiva com a m?dia de TFGe (r=0,250; p=0,008). O fator Socializa??o apresentou m?dias significativamente mais elevadas nos pacientes homens (p<0,001) e em pacientes sem infe??o (p=0,050). Al?m disto, o fator Socializa??o indicou correla??o significativa positiva com a m?dia de creatinina (r= 0,250; p= 0,007) e negativa com TFGe (r=-0,208; p=0,027). O fator Realiza??o apontou n?veis mais altos nos participantes com filhos (p=0,026) e sem uso de medica??es para depress?o (p=0,033), al?m de correla??o positiva com Reatividade contra painel de ant?genos HLA I (r=0,223; p=0,018). No fator Abertura a ?nica diferen?a estat?stica significativa identificada foi em rela??o ? escolaridade que apontou maiores m?dias nos investigados com Ensino Superior (p=0,037). Os resultados sugerem que as caracter?sticas de personalidade podem estar associadas aos resultados do transplante O acompanhamento destes pacientes durante um per?odo maior poder? levar a um melhor entendimento da rela??o entre fatores de personalidade e evolu??o cl?nica no per?odo p?s-transplante

Multi-strange baryon production in pp collisions at √s=7 TeV with ALICE

A measurement of the multi-strange Ξ− and Ω− baryons and their antiparticles by the ALICE experiment at the CERN Large Hadron Collider (LHC) is presented for inelastic proton–proton collisions at a centre-of-mass energy of 7 TeV. The transverse momentum (pT) distributions were studied at mid-rapidity (|y|6.0 GeV/c. We also illustrate the difference between the experimental data and model by comparing the corresponding ratios of (Ω−+Ω¯+)/(Ξ−+Ξ¯+) as a function of transverse mass

Heavy flavour decay muon production at forward rapidity in proton–proton collisions at √s=7 TeV

The production of muons from heavy flavour decays is measured at forward rapidity in proton–proton collisions at √s=7 TeV collected with the ALICE experiment at the LHC. The analysis is carried out on a data sample corresponding to an integrated luminosity Lint=16.5 nb−1. The transverse momentum and rapidity differential production cross sections of muons from heavy flavour decays are measured in the rapidity range 2.5<y<4, over the transverse momentum range 2<pt<12 GeV/c. The results are compared to predictions based on perturbative QCD calculations

Inclusive J/ψ production in pp collisions at √s=2.76 TeV

The ALICE Collaboration has measured inclusive J/ψ production in pp collisions at a center-of-mass energy √s=2.76 TeV at the LHC. The results presented in this Letter refer to the rapidity ranges |y|<0.9 and 2.5<y<4 and have been obtained by measuring the electron and muon pair decay channels, respectively. The integrated luminosities for the two channels are Linte=1.1 nb−1 and Lintμ=19.9 nb−1, and the corresponding signal statistics are NJ/ψe+e−=59±14 and NJ/ψμ+μ−=1364±53. We present dσJ/ψ/dy for the two rapidity regions under study and, for the forward-y range, d2σJ/ψ/dydpt in the transverse momentum domain 0<pt<8 GeV/c. The results are compared with previously published results at s=7 TeV and with theoretical calculations
