Double Parton Scattering, Multi-Parton Interactions, underlying event and identified hadrons: summary of recent results

Recent results related to Double-Parton Scattering (DPS) and Multi-Parton Interactions (MPI) from the LHC experiments (ALICE, ATLAS, CMS and LHCb) are reviewed and discussed together with a brief overview of relevant literature. The robust evidence collected for DPS in different channels at LHC energies is complemented by an increasing understanding of our description of MPI in high energy collisions and the corresponding modelling of the underlying event (UE) in hadronic interactions. Potential new results expected during Run 2 at the LHC are also anticipated. The relation and the interplay between the relevant observables for DPS, MPI and UE analyses are discussed presenting recent attempts to bring together their description in a single Monte Carlo tune. Identified hadron spectra at the LHC have been now measured by all collaborations and results are reviewed with an emphasis on strangeness production and baryon/meson ratio. The data collected during Run 1 at the LHC with different collision systems (pp, p-Pb, Pb-Pb) show that several particle production features appear to be more correlated with the event multiplicity than the collision system itself.Comment: 7 pages, no figures, LHCP2014 conference proceeding

MONOLITH: a next generation experiment for athospheric neutrinos

MONOLITH is a massive magnetized tracking calorimeter, optimized for the detection of atmospheric muon neutrinos, proposed at the Gran Sasso laboratory in Italy. The main goal is to establish (or reject) the neutrino oscillation hypothesis through an explicit observation of the full first oscillation swing (the ``L/E pattern''). Its performance, status and prospects are briefly reviewed.Comment: Talk given at Europhysics Neutrino Oscillation Workshop (NOW2000), Otranto, Italy, September 9-16, 2000 (4 pages, 3 figures

Estimations of the Distances of Stellar Collapses in the Galaxy by Analyzing the Energy Spectrum of Neutrino Bursts

The neutrino telescopes of the present generation, depending on their specific features, can reconstruct the neutrino spectra from a galactic burst. Since the optical counterpart could be not available, it is desirable to have at hand alternative methods to estimate the distance of the supernova explosion using only the neutrino data. In this work we present preliminary results on the method we are proposing to estimate the distance from a galactic supernova based only on the spectral shape of the neutrino burst and assumptions on the gravitational binding energy released an a typical supernova explosion due to stellar collapses.Comment: Proceedings of the Second International Symposium on Strong Electromagnetic Fields and Neutron Stars (SMFNS 2011) Instituto de Cibern\'etica, Matem\'atica y F\'isica (ICIMAF) Sociedad Cubana de F\'isica (SCF) Varadero, Cuba, 5-7 May 201

Física e cultura popular : a poesia do samba na sala de aula

A criatividade é um elemento comum, tanto no trabalho do cientista como do artista e, uma aproximação entre esses dois campos do conhecimento pode facilitar a compreensão da Ciência como lugar de construção de conhecimento que está baseado, dentre outros aspectos, em concepções prévias trazidas por aqueles que participam dessa construção. Este trabalho apresenta parte de uma pesquisa que se baseou na aproximação entre a Física e elementos da cultura popular – a poesia do samba – como mediadora da investigação da origem das concepções alternativas de alunos do ensino médio sobre a reflexão da luz, através de um projeto de parceria entre a universidade e escolas, que envolveu alunos de graduação e ensino médio e que ocorreu no âmbito das escolas, para estudar a origem das concepções alternativas dos alunos, levando-se em conta as concepções de autores de músicas populares

The first experience with a mini-rating scale for the assessment of sexual dysfunction and life-satisfaction in depressed patients in the practice

Even though many scales for the assessment of sexual dysfunction have been recently developed, most of them are suitable rather for the research purpose in clinical trials than to routine interviews in a daily, private practice. We report here the first experience with a simple, semi-quantitative scale for parallel assessment of sexual dysfunction and life-satisfaction (considered to globally reflect the quality of life), which was tested in depressed patients treated in the psychiatric, private practice setting. A combined Sexual Dysfunction(SD-S) and Life-Satisfaction Scale (LS-S), was constructed based on previous interviews with patients. Both consisted of 4-items, assumed to represent core elements of sexual function and individual well-being. The scales were applied to depressed patients treated with any of the SSRIs or with moclobemide, a reversible and selective MAO-A inhibitor. These two treatments were selected for testing the scales because it is known that SSRIs can induce or exacerbate them and moclobemide does not seem to affect them. The selection of treatment modality in this study was, however, entirely at the discretion of the physician. The assessments were done during 3 visits (at baseline, after 2 months and after 4 months). The results of this exploratory trial, testing the applicability, acceptance and utility of a combined mini- SD-S- and LS-S- scale, in 62 depressed patients, showed that the scale: a) was simple to use and well accepted by physicians and patients, b) was a suitable instrument for the practicing physician to control the success of the treatment and c) was sensitively assessing the presence and severity of sexual dysfunction

A Three-Dimensional Code for Muon Propagation through the Rock: MUSIC

We present a new three-dimensional Monte-Carlo code MUSIC (MUon SImulation Code) for muon propagation through the rock. All processes of muon interaction with matter with high energy loss (including the knock-on electron production) are treated as stochastic processes. The angular deviation and lateral displacement of muons due to multiple scattering, as well as bremsstrahlung, pair production and inelastic scattering are taken into account. The code has been applied to obtain the energy distribution and angular and lateral deviations of single muons at different depths underground. The muon multiplicity distributions obtained with MUSIC and CORSIKA (Extensive Air Shower simulation code) are also presented. We discuss the systematic uncertainties of the results due to different muon bremsstrahlung cross-sections.Comment: 24 pages, 11 Postscript figures, LaTeX, to be published in Astroparticle Physic
