    An accreditation model that ensures the quality improvement of a college level study program
    (Universidad de Granada, 2020-12-01)
    Tras el análisis de la importancia de la educación superior universitaria, su impacto en el desarrollo de los países y los conflictos que generan el balance entre una autorregulación, respaldada en la autonomía universitaria, y la regulación externa, se evidencia que, la falta de calidad en los procesos formativos y su coherencia con el mercado laboral, termina siendo la opción en como los gobiernos incrementan la regulación externa. Esto se ve reflejado de una manera u otra, en el sistema educativo universitario peruano y en sus procesos de acreditación. En este artículo, se pretende realizar un análisis comparativo con la experiencia de otros países con modelos de acreditación más eficaces, para ello se identifica: (i) la evaluación de la investigación; (ii) la implementación de sistemas de gestión que aseguren la calidad de la institución educativa y; (iii) la formación de evaluadores externos como los elementos diferenciadores, sobre los cuales se establecen alternativas de trabajo en los estándares de acreditación y en los programas de capacitación de pares evaluadores. Además, se enmarca la problemática en la época de la pandemia ocasionada por la Covid-19.

    Dimensions of wisdom perception across twelve countries on five continents
    (Nature Research, 2024-12-01)
    Wisdom is the hallmark of social judgment, but how people across cultures recognize wisdom remains unclear—distinct philosophical traditions suggest different views of wisdom’s cardinal features. We explore perception of wise minds across 16 socio-economically and culturally diverse convenience samples from 12 countries. Participants assessed wisdom exemplars, non-exemplars, and themselves on 19 socio-cognitive characteristics, subsequently rating targets’ wisdom, knowledge, and understanding. Analyses reveal two positively related dimensions—Reflective Orientation and Socio-Emotional Awareness. These dimensions are consistent across the studied cultural regions and interact when informing wisdom ratings: wisest targets—as perceived by participants—score high on both dimensions, whereas the least wise are not reflective but moderately socio-emotional. Additionally, individuals view themselves as less reflective but more socio-emotionally aware than most wisdom exemplars. Our findings expand folk psychology and social judgment research beyond the Global North, showing how individuals perceive desirable cognitive and socio-emotional qualities, and contribute to an understanding of mind perception.

    Systematic study of flow vector fluctuations in √sNN = 5.02 TeV Pb–Pb collisions
    (American Physical Society, 2024-06-01)
    Measurements of the pT-dependent flow vector fluctuations in Pb-Pb collisions at sNN=5.02TeV using azimuthal correlations with the ALICE experiment at the Large Hadron Collider are presented. A four-particle correlation approach [ALICE Collaboration, Phys. Rev. C 107, L051901 (2023)2469-998510.1103/PhysRevC.107.L051901] is used to quantify the effects of flow angle and magnitude fluctuations separately. This paper extends previous studies to additional centrality intervals and provides measurements of the pT-dependent flow vector fluctuations at sNN=5.02TeV with two-particle correlations. Significant pT-dependent fluctuations of the V - 2 flow vector in Pb-Pb collisions are found across different centrality ranges, with the largest fluctuations of up to ∼15% being present in the 5% most central collisions. In parallel, no evidence of significant pT-dependent fluctuations of V - 3 or V - 4 is found. Additionally, evidence of flow angle and magnitude fluctuations is observed with more than 5σ significance in central collisions. These observations in Pb-Pb collisions indicate where the classical picture of hydrodynamic modeling with a common symmetry plane breaks down. This has implications for hard probes at high pT, which might be biased by pT-dependent flow angle fluctuations of at least 23% in central collisions. Given the presented results, existing theoretical models should be reexamined to improve our understanding of initial conditions, quark-gluon plasma properties, and the dynamic evolution of the created system.

    Simultaneous Measurement of Muon Neutrino νμ Charged-Current Single π+ Production in CH, C, H2O, Fe, and Pb Targets in MINERvA
    (American Physical Society, 2023-07-07)
    Neutrino-induced charged-current single π+ production in the Δ(1232) resonance region is of considerable interest to accelerator-based neutrino oscillation experiments. In this Letter, high statistic differential cross sections are reported for the semiexclusive reaction νμA→μ-π++ nucleon(s) on scintillator, carbon, water, iron, and lead targets recorded by MINERvA using a wideband νμ beam with Eν ≈6 GeV. Suppression of the cross section at low Q2 and enhancement of low Tπ are observed in both light and heavy nuclear targets compared with phenomenological models used in current neutrino interaction generators. The cross sections per nucleon for iron and lead compared with CH across the kinematic variables probed are 0.8 and 0.5 respectively, a scaling which is also not predicted by current generators.

    On the Sensitivity Reach of LQ Production with Preferential Couplings to Third Generation Fermions at the LHC
    (Institute for Ionics, 2023-11-01)
    Leptoquarks (LQ s) are hypothetical particles that appear in various extensions of the Standard Model (SM), that can explain observed differences between SM theory predictions and experimental results. The production of these particles has been widely studied at various experiments, most recently at the Large Hadron Collider (LHC), and stringent bounds have been placed on their masses and couplings, assuming the simplest beyond-SM (BSM) hypotheses. However, the limits are significantly weaker for LQ models with family non-universal couplings containing enhanced couplings to third-generation fermions. We present a new study on the production of a LQ at the LHC, with preferential couplings to third-generation fermions, considering proton-proton collisions at s=13TeV and s=13.6TeV . Such a hypothesis is well motivated theoretically and it can explain the recent anomalies in the precision measurements of B -meson decay rates, specifically the RD(∗) ratios. Under a simplified model where the LQ masses and couplings are free parameters, we focus on cases where the LQ decays to a τ lepton and a b quark, and study how the results are affected by different assumptions about chiral currents and interference effects with other BSM processes with the same final states, such as diagrams with a heavy vector boson, Z ′ . The analysis is performed using machine learning techniques, resulting in an increased discovery reach at the LHC, allowing us to probe new physics phase space which addresses the B -meson anomalies, for LQ masses up to 5.00TeV , for the high luminosity LHC scenario.

    Measurement of the Lifetime and Λ Separation Energy of HΛ3
    (American Physical Society, 2023-09-08)
    The most precise measurements to date of the HΛ3 lifetime τ and Λ separation energy BΛ are obtained using the data sample of Pb-Pb collisions at sNN=5.02 TeV collected by ALICE at the LHC. The HΛ3 is reconstructed via its charged two-body mesonic decay channel (HΛ3→He3+π- and the charge-conjugate process). The measured values τ=[253±11(stat)±6(syst)] ps and BΛ=[102±63(stat)±67(syst)] keV are compatible with predictions from effective field theories and confirm that the HΛ3 structure is consistent with a weakly bound system.

    Constraining the K¯N Coupled Channel Dynamics Using Femtoscopic Correlations at the LHC
    (Institute for Ionics, 2023-04-01)
    The interaction of K - with protons is characterised by the presence of several coupled channels, systems like K ¯ n and π Σ with a similar mass and the same quantum numbers as the K - p state. The strengths of these couplings to the K - p system are of crucial importance for the understanding of the nature of the Λ (1405) resonance and of the attractive K - p strong interaction. In this article, we present measurements of the K - p correlation functions in relative momentum space obtained in pp collisions at s=13 Te, in p–Pb collisions at sNN=5.02 Te, and (semi)peripheral Pb–Pb collisions at sNN=5.02 Te. The emitting source size, composed of a core radius anchored to the K + p correlation and of a resonance halo specific to each particle pair, varies between 1 and 2 fm in these collision systems. The strength and the effects of the K ¯ n and π Σ inelastic channels on the measured K - p correlation function are investigated in the different colliding systems by comparing the data with state-of-the-art models of chiral potentials. A novel approach to determine the conversion weights ω , necessary to quantify the amount of produced inelastic channels in the correlation function, is presented. In this method, particle yields are estimated from thermal model predictions, and their kinematic distribution from blast-wave fits to measured data. The comparison of chiral potentials to the measured K - p interaction indicates that, while the π Σ – K - p dynamics is well reproduced by the model, the coupling to the K ¯ n channel in the model is currently underestimated.

    Can SUSY Relax Lepton Number Violation Constraints Coming from Loop Corrections to Light Neutrino Masses on the Low-Scale Seesaw Mechanism?
    (American Physical Society, 2023-06-01)
    Heavy neutrinos from the type-I seesaw model can have a large mixing with active states, motivating their search at collider experiments. However, loop corrections to light neutrino masses constrain the heavy neutrinos to appear in pseudo-Dirac pairs, leading to a potential suppression of lepton number violating parameters. In this work we perform a detailed review of a proposal to relax constraints on lepton number violation by adding supersymmetry (SUSY). We define the conditions necessary to maximize the SUSY screening effect, with the objective of allowing a larger mass splitting between low-scale heavy neutrino masses. We find that the sole addition of SUSY does not guarantee a screening, and that favorable cases have some degree of fine-tuning.
