    El conflicto es inherente a las relaciones humanas, es así, como la dinámica se reproduce en cualquier ámbito donde interactúen personas. Sin embargo, la violencia es sólo una de las posibilidades para resolver una situación conflictiva, en este artículo se mostrarán diversas maneras de solucionar los problemas desde la pedagogía. El propósito de la investigación fue generar espacios de construcción de paz y convivencia a través de la investigación como estrategia pedagógica (IEP). El Estudio se centró bajo el enfoque cualitativo, desde el tipo de investigación acción. La población de este estudio estuvo constituida por cuarenta (40) estudiantes del grado sexto de bachillerato de la IED Humberto Velázquez García. Los resultados evidenciaron poca comprensión y respeto de los derechos humanos, falta de concepción democrática, lo que desmejora la construcción de relaciones interpersonales e institucionales y culturales justas, propiciando falencias en el fortalecimiento de los valores en las instituciones.The conflict is inherent in human relations, is thus, as Dynamics is reproduced in any area where people interact.

This study population consisted of forty (40) students of the sixth grade of Bachelor of the FDI Humberto Velázquez Garcia. The results showed little understanding and respect of human rights, lack of democratic conception, what fair demotion the construction of interpersonal and institutional and cultural relations, leading to flaws in the strengthening of the values in the institutions

    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

    Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

    This paper presents measurements of the W+μ+νW^+ \rightarrow \mu^+\nu and WμνW^- \rightarrow \mu^-\nu cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

    Evidence for the Higgs-boson Yukawa coupling to tau leptons with the ATLAS detector

    Results of a search for H → τ τ decays are presented, based on the full set of proton-proton collision data recorded by the ATLAS experiment at the LHC during 2011 and 2012. The data correspond to integrated luminosities of 4.5 fb−1 and 20.3 fb−1 at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV respectively. All combinations of leptonic (τ → `νν¯ with ` = e, µ) and hadronic (τ → hadrons ν) tau decays are considered. An excess of events over the expected background from other Standard Model processes is found with an observed (expected) significance of 4.5 (3.4) standard deviations. This excess provides evidence for the direct coupling of the recently discovered Higgs boson to fermions. The measured signal strength, normalised to the Standard Model expectation, of µ = 1.43 +0.43 −0.37 is consistent with the predicted Yukawa coupling strength in the Standard Model
