La presente investigación titulada satisfacción laboral, su relación con productividad en trabajadores del área atención domiciliaria en un establecimiento de salud, Chimbote 2023, tuvo como objetivo general; determinar la relación entre satisfacción laboral, la productividad en trabajadores del área atención domiciliaria en establecimiento de salud, Chimbote 2023. Se desarrolló bajo una metodología de tipo aplicada con un enfoque cuantitativo, siendo descriptivo correlacional, con un diseño no experimental con corte transversal. Asimismo, la muestra estuvo conformada por 52 colaboradores y el instrumento utilizado fue el cuestionario. Los resultados obtenidos fueron; con respecto a la hipótesis se concluye que existe una correlación positiva alta 0.756. Además, el valor p fue significativo con un (p=0,000), por lo que se rechazó la hipótesis nula, en su lugar, se aceptó la hipótesis de investigación, que existe una relación significativa entre las variables del estudio. Respecto a la variable satisfacción laboral el nivel predominante fue el medio con un 55.77% y en relación con la segunda variable el 55.8%, presento un nivel medio. Finalmente se concluye que existe un nivel de correlación positivo alto con un nivel correlacional de Spearman de 0,756

Measurement of the Splitting Function in &ITpp &ITand Pb-Pb Collisions at root&ITsNN&IT=5.02 TeV

Data from heavy ion collisions suggest that the evolution of a parton shower is modified by interactions with the color charges in the dense partonic medium created in these collisions, but it is not known where in the shower evolution the modifications occur. The momentum ratio of the two leading partons, resolved as subjets, provides information about the parton shower evolution. This substructure observable, known as the splitting function, reflects the process of a parton splitting into two other partons and has been measured for jets with transverse momentum between 140 and 500 GeV, in pp and PbPb collisions at a center-of-mass energy of 5.02 TeV per nucleon pair. In central PbPb collisions, the splitting function indicates a more unbalanced momentum ratio, compared to peripheral PbPb and pp collisions.. The measurements are compared to various predictions from event generators and analytical calculations.Peer reviewe

Inclusive Search for a Highly Boosted Higgs Boson Decaying to a Bottom Quark-Antiquark Pair

© 2018 CERN. An inclusive search for the standard model Higgs boson (H) produced with large transverse momentum (pT) and decaying to a bottom quark-antiquark pair (bb) is performed using a data set of pp collisions at s=13 TeV collected with the CMS experiment at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb-1. A highly Lorentz-boosted Higgs boson decaying to bb is reconstructed as a single, large radius jet, and it is identified using jet substructure and dedicated b tagging techniques. The method is validated with Z→bb decays. The Z→bb process is observed for the first time in the single-jet topology with a local significance of 5.1 standard deviations (5.8 expected). For a Higgs boson mass of 125 GeV, an excess of events above the expected background is observed (expected) with a local significance of 1.5 (0.7) standard deviations. The measured cross section times branching fraction for production via gluon fusion of H→bb with reconstructed pT > 450 GeV and in the pseudorapidity range -2.5 < η < 2.5 is 74±48(stat)-10+17(syst) fb, which is consistent within uncertainties with the standard model prediction

Search for excited quarks of light and heavy flavor in γ\gamma+jet final state in proton-proton collisions at s=\sqrt{s} = 13 TeV

A search is presented for excited quarks of light and heavy flavor that decay to $\gamma$+jet final states. The analysis is based on data corresponding to an integrated luminosity of 35.9 fb$^{-1}$ collected by the CMS experiment in proton-proton collisions at $\sqrt{s}=$ 13 TeV at the LHC. A signal would appear as a resonant contribution to the invariant mass spectrum of the $\gamma$+jet system, above the background expected from standard model processes. No resonant excess is found, and upper limits are set on the product of the excited quark cross section and its branching fraction as a function of its mass. These are the most stringent limits to date in the $\gamma$+jet final state, and exclude excited light quarks with masses below 5.5 TeV and excited b quarks with masses below 1.8 TeV, assuming standard model couplings

Search for Zγ\gamma resonances using leptonic and hadronic final states in proton-proton collisions at s=\sqrt{s}= 13 TeV

A search is presented for resonances decaying to a Z boson and a photon. The analysis is based on data from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb$^{-1}$, and collected with the CMS detector at the LHC in 2016. Two decay modes of the Z boson are investigated. In the leptonic channels, the Z boson candidates are reconstructed using electron or muon pairs. In the hadronic channels, they are identified using a large-radius jet, containing either light-quark or b quark decay products of the Z boson, via jet substructure and advanced b quark tagging techniques. The results from these channels are combined and interpreted in terms of upper limits on the product of the production cross section and the branching fraction to Z$\gamma$ for narrow and broad spin-0 resonances with masses between 0.35 and 4.0 TeV, providing thereby the most stringent limits on such resonances
