    Resumen. Este estudio se centra en el análisis de las posturas y movimientos inadecuados de las personas que trabajan en el sector informal, lo que puede provocar trastornos musculo esqueléticos que generan daños en músculos, tendones y nervios. La espalda, el cuello, los hombros, los codos y las muñecas buscando cambios alternativos positivos para mejorar las condiciones laborales de estos trabajadores, que en muchas ocasiones no cuentan con los recursos económicos disponibles para solucionar sus problemas, por ello se da la creación del presente manual ergonómico para vendedores ambulantes. Se realizó una encuesta que aporta nuevos conocimientos que pueden ayudar a encontrar soluciones a este problema, así como alternativas para comprender las tareas que las personas que laboran en la zona realizan de manera informal y para que estas las puedan trabajar adecuadamente. Se realiza el diagnóstico de las condiciones laborales de las personas que trabajan en las calles aledañas al Centro de Kennedy se basa en métodos conocidos para tal fin. A partir de la aplicación de la encuesta, se analizaron los resultados, por lo que basados en estos se hizo el manual, para mejorar la calidad de vida de las personas.Abstract This study focuses on the analysis of the inappropriate postures and movements of people who work in the informal sector, which can cause musculoskeletal disorders that cause damage to muscles, tendons and nerves. The back, neck, shoulders, elbows and wrists looking for positive alternative changes to improve the working conditions of these workers, who in many cases do not have the financial resources available to solve their problems, therefore the creation of the This ergonomic manual for street vendors. A survey was carried out that provides new knowledge that can help find solutions to this problem, as well as alternatives to understand the tasks that people who work in the area perform informally and so that they can work them properly. The diagnosis of the working conditions of the people who work in the streets surrounding the Kennedy Center is based on known methods for this purpose. From the application of the survey, the results were analyzed, so based on these the manual was made to improve people's quality of life.Tabla de Contenido CAPÍTULO 1 PROGRAMA DE INTERVENCIÓN PARA DESÓRDENES MUSCULO ESQUELÉTICOS EN TRABAJADORES INFORMALES DEL SECTOR COMERCIAL EN LA LOCALIDAD DE KENNEDY BOGOTÁ. 13 Título 1 Planteamiento del problema. 16 1.1.

    Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

    The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum

    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
