    En la actualidad, para el abordaje del proceso salud-enfermedad se requiere, además de controlar la enfermedad, preservar en lo posible la calidad de vida de la persona. En este sentido, el objetivo del presente trabajo fue identificar la relación entre la gaudibilidad y la percepción del estado de salud en una muestra de mexicanos, y comparar dichas variables según el género de los participantes. Para esto, se utilizó un diseño transversal y correlacional con la aplicación de la Escala de Gaudibilidad y la versión corta del Cuestionario de Salud (SF-36). En total, participaron 285 personas de entre 14 y 78 años (M = 32.13, DE = 13.38), reclutados por medio de la técnica de bola de nieve, con quienes se formó una muestra no probabilística. Los resultados indicaron una relación estadísticamente significativa, positiva y moderada entre la gaudibilidad y la salud general de los participantes (p = .407, p < .001), debido a que las personas con alta gaudibilidad percibieron menos riesgos en salud general en comparación con las personas con baja y moderada gaudibilidad (RM = 4.527, 2.434 - 8.419). Asimismo, se identificó una diferencia estadísticamente significativa en cuanto al género en los factores funcionamiento físico (z = -2.293, p = .022) y salud mental (z = -2.243, p = .025) del SF-36, ya que los hombres refirieron un nivel mayor en ambos casos. Se concluye que la gaudibilidad tiene una influencia relevante sobre la percepción del estado de salud.Na atualidade, para a abordagem do processo saúde-doença requer-se, além de controlar a doença, preservar, na medida do possível, a qualidade de vida da pessoa.

Igualmente, identificou-se uma diferença estatisticamente significativa com respeito ao gênero nos fatores funcionamento físico (z = -2.293, p = .022) e saúde mental (z = -2.243, p = .025) do SF-36, já que os homens indicaram um maior nível em ambos os casos. Conclui-se que a gaudibilidade tem uma influência relevante sobre a percepção do estado de saúde.The current approach to the health-illness process requires, in addition to disease control, the preservation of the person's quality of life. This study has the purpose of identifying the relationship between gaudiebility and the perception of health status in a Mexican sample, as well as comparing these variables by gender. A cross-sectional and correlational study was conducted for such purposes. Gaudiebility was measured with the Gaudiebility Scale and the perception of health status with the MOS 36-Item Short-Form Health Survey (SF-36). The sample consisted of 285 people between the ages of 14 and 78 (M = 32.13, SD = 13.38), who were recruited with the snowball sampling method, forming a non-probability sample. Results indicate a statistically significant positive and moderate relationship between gaudiebility and the General Health of people (p = .433, p < .001). Thus, people with high gaudiebility perceive less risks to their General Health compared with people who have low and moderate gaudiebility (RM = 4.527, 2.434 - 8.419). Furthermore, a statistically significant difference was identified by gender regarding Physical Functioning (z = -2.293, p = .022) and Mental Health (z = -2.243, p = .025) on the SF-36, where men reported a higher level in both cases. It was concluded that gaudiebility has a relevant influence on the perception of health status

    Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| &lt; 0.03 at 95% confidence level.

    The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe

    Search for Physics beyond the Standard Model in Events with Overlapping Photons and Jets

    Results are reported from a search for new particles that decay into a photon and two gluons, in events with jets. Novel jet substructure techniques are developed that allow photons to be identified in an environment densely populated with hadrons. The analyzed proton-proton collision data were collected by the CMS experiment at the LHC, in 2016 at root s = 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). The spectra of total transverse hadronic energy of candidate events are examined for deviations from the standard model predictions. No statistically significant excess is observed over the expected background. The first cross section limits on new physics processes resulting in such events are set. The results are interpreted as upper limits on the rate of gluino pair production, utilizing a simplified stealth supersymmetry model. The excluded gluino masses extend up to 1.7 TeV, for a neutralino mass of 200 GeV and exceed previous mass constraints set by analyses targeting events with isolated photons.Peer reviewe

    Measurement of b jet shapes in proton-proton collisions at root s=5.02 TeV

    We present the first study of charged-hadron production associated with jets originating from b quarks in proton-proton collisions at a center-of-mass energy of 5.02 TeV. The data sample used in this study was collected with the CMS detector at the CERN LHC and corresponds to an integrated luminosity of 27.4 pb(-1). To characterize the jet substructure, the differential jet shapes, defined as the normalized transverse momentum distribution of charged hadrons as a function of angular distance from the jet axis, are measured for b jets. In addition to the jet shapes, the per-jet yields of charged particles associated with b jets are also quantified, again as a function of the angular distance with respect to the jet axis. Extracted jet shape and particle yield distributions for b jets are compared with results for inclusive jets, as well as with the predictions from the pythia and herwig++ event generators.Peer reviewe

    Measurement of the azimuthal anisotropy of Y(1S) and Y(2S) mesons in PbPb collisions at root s(NN)=5.02 TeV

    The second-order Fourier coefficients (v(2)) characterizing the azimuthal distributions of Y(1S) and Y(2S) mesons produced in PbPb collisions at root s(NN) = 5.02 TeV are studied. The Y mesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. The collected data set corresponds to an integrated luminosity of 1.7 nb(-1). The scalar product method is used to extract the v2 coefficients of the azimuthal distributions. Results are reported for the rapidity range vertical bar y vertical bar < 2.4, in the transverse momentum interval 0 < pT < 50 GeV/c, and in three centrality ranges of 10-30%, 30-50% and 50-90%. In contrast to the J/psi mesons, the measured v(2) values for the Y mesons are found to be consistent with zero. (C) 2021 The Author(s). Published by Elsevier B.V.Peer reviewe

    An embedding technique to determine ττ backgrounds in proton-proton collision data

    Get PDF
    An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe
