Ilustraciones y judaísmo

Kant distingue en ¿Qué es la Ilustración? entre "tiempos ilustrados" y "tiempos de Ilustración". Los primeros serían los propios de una época toda ella informada por la razón. Todas las actividades del hombre -la ética, la estética, la política etc. conformadas por la razón. Tiempos razonables y racionales. Pero no estamos tan lejos. Los nuestros son modestos "tiempos de Ilustración" en los que la Ilustración está en marcha, pero a sabiendas de que queda un gran trecho por recorrer hasta llegar a la meta o, dicho de otra manera, a sabiendas de que hay que aguantar por el momento mucho oscurantismo

La memoria, principio de la justicia

Manuel Reyes Mate, uno de los máximos exponentes de la ética anamnética en lengua castellana, desarrolla, en este artículo, una investigación de la virtud de la justicia a partir de la memoria de las víctimas. En su artículo critica, a la vez, la noción de justicia que deriva de las éticas dialógicas o del consenso representadas por Jürgen Habermas y por John Rawls. PALABRAS CLAVE: Memoria, justicia, ética, víctimas. Memory, principle of justice ABSTRACT: Manuel Reyes Mate, one of the most outstanding figures of anamnesis philosophy in Spanish, develops in this article a research on the virtue of justice from the memory of victims. In his article, he also criticizes the concept of justice derived from discourse or consensus ethics represented by Jürgen Habermas and John Rawls. KEY-WORDS: Memory, justice, ethics, victims

White Paper 1: New foundations for a sustainable global society

Coordinación: Eduardo Moyano Estrada; Tomás García Azcárate.This volume is focused on the axis “New foundations for a sustainable global society”, and refers to the important process of global change that affects all dimensions of society, disrupting the context in which scientific work has been developed in recent decades. It is a process of change not comparable to what happened decades ago, mainly due to its breadth, multidimensionality and interdependence, and also to the fact that this process manifests itself simultaneously in many areas, territories and social groups. Its analysis therefore requires carrying out a convergence exercise between areas and lines of research, betting on a multidisciplinary approach, since both “globalization” and “sustainability” are, concepts that affect society, as a whole.Peer reviewe

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

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| < 0.03 at 95% confidence level.

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

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

Measurement of nuclear modification factors of gamma(1S)), gamma(2S), and gamma(3S) mesons in PbPb collisions at root s(NN)=5.02 TeV

The cross sections for ϒ(1S), ϒ(2S), and ϒ(3S) production in lead-lead (PbPb) and proton-proton (pp) collisions at √sNN = 5.02 TeV have been measured using the CMS detector at the LHC. The nuclear modification factors, RAA, derived from the PbPb-to-pp ratio of yields for each state, are studied as functions of meson rapidity and transverse momentum, as well as PbPb collision centrality. The yields of all three states are found to be significantly suppressed, and compatible with a sequential ordering of the suppression, RAA(ϒ(1S)) > RAA(ϒ(2S)) > RAA(ϒ(3S)). The suppression of ϒ(1S) is larger than that seen at √sNN = 2.76 TeV, although the two are compatible within uncertainties. The upper limit on the RAA of ϒ(3S) integrated over pT, rapidity and centrality is 0.096 at 95% confidence level, which is the strongest suppression observed for a quarkonium state in heavy ion collisions to date. © 2019 The Author(s).
