La imagen y la narrativa como herramientas para el abordaje psicosocial en escenarios de violencia. Municipios Guadalupe, Pitalito e Ibagué

El presente informe pretende dar a conocer el desarrollo del paso cuatro del diplomado de profundización acompañamiento psicosocial en escenarios de violencia que tiene como objetivo que los estudiantes sean capaces de evaluar eventos psicosociales traumáticos desde el enfoque narrativo y el análisis del relato para proponer recursos de afrontamiento psicosocial al sufrimiento por violencia. Para ello se realizó una contextualización del entorno y por medio del ejercicio de foto voz, se representaron los diferentes tipos de violencia por el conflicto armado, las fotografías fueron tomadas en los diferentes sitios de residencia de cada uno de los estudiantes; posteriormente se intentó fotografiar aspectos positivos, donde la comunidad ha logrado reconstruir su bienestar y trasformar su realidad en una mejor calidad de vida, pues han generado comportamientos resilientes. De este modo el grupo colaborativo luego de realizar las lecturas de los contenidos y la visualización de los recursos sugeridos, se procede a realizar un análisis y reflexión del relato protagonizado por Carlos Arturo quien fue una víctima de una mina antipersonal en su adolescencia, teniendo en cuenta los interrogantes sugeridos. De igual modo teniendo en cuenta el relato se proponen algunas preguntas, teniendo en cuenta si se tuviera la oportunidad de entrevistar al protagonista del relato, estas preguntas se clasifican en estratégicas, circulares y reflexivas, que están orientadas hacia un acercamiento psicosocial ético y proactivo en relación a la superación de las condiciones de victimización. Otras de las actividades desarrolladas es el análisis del caso del municipio de Peñas Coloradas, siendo esta una comunidad que huyo del hambre y la miseria, y encontraron en el cultivo de la coca una solución a sus problemas, por tal razón la comunidad fue estigmatizada y desplazada nuevamente, volviendo a su condición de vulnerabilidad, ellos han buscado por varios medios regresar a su tierra, pero no se lo han permitido, es por eso que a partir de estos hechos, se describen propuestas de acciones y estrategias de acompañamiento psicosocial, que contribuyan al afrontamiento de las consecuencias a raíz de la violencia y se fomente la resiliencia para así contribuir al mejoramiento de la calidad de vida de la comunidad.This report aims to present the development of step four of the diploma of in-depth psychosocial accompaniment in violence scenarios that aims for students to be able to evaluate traumatic psychosocial events from the narrative approach and the analysis of the story to propose coping resources psychosocial to suffering from violence. To do this, a contextualization of the environment was carried out and by means of the photo-voice exercise, the different types of violence due to the armed conflict were represented, the photographs were taken in the different places of residence of each of the students; Later, they tried to photograph positive aspects, where the community has managed to rebuild their well-being and transform their reality into a better quality of life, since they have generated resilient behaviors. In this way, the collaborative group, after reading the contents and visualizing the suggested resources, proceeds to carry out an analysis and reflection of the story starring Carlos Arturo who was a victim of an antipersonnel mine in his adolescence, taking into account count the suggested questions. In the same way, taking into account the story, some questions are proposed, taking into account if one had the opportunity to interview the protagonist of the story, these questions are classified as strategic, circular and reflective, which are oriented towards an ethical and proactive psychosocial approach in relation to overcoming victimization conditions. Another of the activities carried out is the analysis of the case of the municipality of Peñas Coloradas, this being a community that fled from hunger and misery, and found in the cultivation of coca a solution to its problems, for this reason the community was stigmatized and displaced again, returning to their condition of vulnerability, they have sought by various means to return to their land, but they have not allowed it, that is why, based on these facts, proposals for actions and strategies of psychosocial support are described, which contribute to coping with the consequences of violence and promote resilience in order to contribute to the improvement of the community's quality of life

Measurement of the tt¯tt¯ production cross section in pp collisions at √s=13 TeV with the ATLAS detector

A measurement of four-top-quark production using proton-proton collision data at a centre-of-mass energy of 13 TeV collected by the ATLAS detector at the Large Hadron Collider corresponding to an integrated luminosity of 139 fb−1 is presented. Events are selected if they contain a single lepton (electron or muon) or an opposite-sign lepton pair, in association with multiple jets. The events are categorised according to the number of jets and how likely these are to contain b-hadrons. A multivariate technique is then used to discriminate between signal and background events. The measured four-top-quark production cross section is found to be 26+17−15 fb, with a corresponding observed (expected) significance of 1.9 (1.0) standard deviations over the background-only hypothesis. The result is combined with the previous measurement performed by the ATLAS Collaboration in the multilepton final state. The combined four-top-quark production cross section is measured to be 24+7−6 fb, with a corresponding observed (expected) signal significance of 4.7 (2.6) standard deviations over the background-only predictions. It is consistent within 2.0 standard deviations with the Standard Model expectation of 12.0 ± 2.4 fb

Measurements of sensor radiation damage in the ATLAS inner detector using leakage currents

Non-ionizing energy loss causes bulk damage to the silicon sensors of the ATLAS pixel and strip detectors. This damage has important implications for data-taking operations, charged-particle track reconstruction, detector simulations, and physics analysis. This paper presents simulations and measurements of the leakage current in the ATLAS pixel detector and semiconductor tracker as a function of location in the detector and time, using data collected in Run 1 (2010–2012) and Run 2 (2015–2018) of the Large Hadron Collider. The extracted fluence shows a much stronger |z|-dependence in the innermost layers than is seen in simulation. Furthermore, the overall fluence on the second innermost layer is significantly higher than in simulation, with better agreement in layers at higher radii. These measurements are important for validating the simulation models and can be used in part to justify safety factors for future detector designs and interventions.publishedVersio

Measurements of W+W−+ ≥ 1 jet production cross-sections in pp collisions at s \sqrt{s} = 13 TeV with the ATLAS detector

Fiducial and differential cross-section measurements of W+W− production in association with at least one hadronic jet are presented. These measurements are sensitive to the properties of electroweak-boson self-interactions and provide a test of perturbative quantum chromodynamics and the electroweak theory. The analysis is performed using proton-proton collision data collected at p s = 13TeV with the ATLAS experiment, corresponding to an integrated luminosity of 139 fb−1. Events are selected with exactly one oppositely charged electron-muon pair and at least one hadronic jet with a transverse momentum of pT > 30 GeV and a pseudorapidity of |�| < 4.5. After subtracting the background contributions and correcting for detector effects, the jet-inclusive W+W−+ � 1 jet fiducial cross-section and W+W−+ jets differential cross-sections with respect to several kinematic variables are measured. These measurements include leptonic quantities, such as the lepton transverse momenta and the transverse mass of the W+W− system, as well as jet-related observables such as the leading jet transverse momentum and the jet multiplicity. Limits on anomalous triple-gauge-boson couplings are obtained in a phase space where interference between the Standard Model amplitude and the anomalous amplitude is enhanced

Measurement of the energy asymmetry in t(t)over-barj production at 13 TeV with the ATLAS experiment and interpretation in the SMEFT framework

A measurement of the energy asymmetry in jet-associated top-quark pair production is presented using $$139\,{\mathrm {fb}}^{-1}$$ 139 fb - 1 of data collected by the ATLAS detector at the Large Hadron Collider during pp collisions at $$\sqrt{s}=13\,\text {TeV}$$ s = 13 TeV . The observable measures the different probability of top and antitop quarks to have the higher energy as a function of the jet scattering angle with respect to the beam axis. The energy asymmetry is measured in the semileptonic $$t{\bar{t}}$$ t t ¯ decay channel, and the hadronically decaying top quark must have transverse momentum above $$350\,\text {GeV}$$ 350 GeV . The results are corrected for detector effects to particle level in three bins of the scattering angle of the associated jet. The measurement agrees with the SM prediction at next-to-leading-order accuracy in quantum chromodynamics in all three bins. In the bin with the largest expected asymmetry, where the jet is emitted perpendicular to the beam, the energy asymmetry is measured to be $$-0.043\pm 0.020$$ - 0.043 ± 0.020 , in agreement with the SM prediction of $$-0.037\pm 0.003$$ - 0.037 ± 0.003 . Interpreting this result in the framework of the Standard Model effective field theory (SMEFT), it is shown that the energy asymmetry is sensitive to the top-quark chirality in four-quark operators and is therefore a valuable new observable in global SMEFT fits

Search for neutral long-lived particles in pp collisions at √s = 13 TeV that decay into displaced hadronic jets in the ATLAS calorimeter

A search for decays of pair-produced neutral long-lived particles (LLPs) is presented using 139 fb−1 of proton-proton collision data collected by the ATLAS detector at the LHC in 2015–2018 at a centre-of-mass energy of 13 TeV. Dedicated techniques were developed for the reconstruction of displaced jets produced by LLPs decaying hadronically in the ATLAS hadronic calorimeter. Two search regions are defined for different LLP kinematic regimes. The observed numbers of events are consistent with the expected background, and limits for several benchmark signals are determined. For a SM Higgs boson with a mass of 125 GeV, branching ratios above 10% are excluded at 95% confidence level for values of c times LLP mean proper lifetime in the range between 20 mm and 10 m depending on the model. Upper limits are also set on the cross-section times branching ratio for scalars with a mass of 60 GeV and for masses between 200 GeV and 1 TeV. [Figure not available: see fulltext.

Measurement and interpretation of same-sign W boson pair production in association with two jets in pp collisions at s = 13 TeV with the ATLAS detector

This paper presents the measurement of fducial and diferential cross sections for both the inclusive and electroweak production of a same-sign W-boson pair in association with two jets (W±W±jj) using 139 fb−1 of proton-proton collision data recorded at a centre-of-mass energy of √s = 13 TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed by selecting two same-charge leptons, electron or muon, and at least two jets with large invariant mass and a large rapidity diference. The measured fducial cross sections for electroweak and inclusive W±W±jj production are 2.92 ± 0.22 (stat.) ± 0.19 (syst.)fb and 3.38±0.22 (stat.)±0.19 (syst.)fb, respectively, in agreement with Standard Model predictions. The measurements are used to constrain anomalous quartic gauge couplings by extracting 95% confdence level intervals on dimension-8 operators. A search for doubly charged Higgs bosons H±± that are produced in vector-boson fusion processes and decay into a same-sign W boson pair is performed. The largest deviation from the Standard Model occurs for an H±± mass near 450 GeV, with a global signifcance of 2.5 standard deviations
