Sensitivity of the SHiP experiment to Heavy Neutral Leptons

Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many extensions of the Standard Model. These particles can, among other things, explain the origin of neutrino masses, generate the observed matter-antimatter asymmetry in the Universe and provide a dark matter candidate. The SHiP experiment will be able to search for HNLs produced in decays of heavy mesons and travelling distances ranging between $\mathcal{O}(50\text{ m})$ and tens of kilometers before decaying. We present the sensitivity of the SHiP experiment to a number of HNL's benchmark models and provide a way to calculate the SHiP's sensitivity to HNLs for arbitrary patterns of flavour mixings. The corresponding tools and data files are also made publicly available.Comment: journal versio

Au-delà de la solidarité féminine

Dans cet article, l’auteure examine la problématique de l’identité et de la différence dans la théorie féministe et le mouvement des femmes du Québec. Les antécédents historiques et la situation actuelle des femmes noires au Québec illustrent les lacunes des principaux modèles de théorisation féministe. Ces modèles ont toujours à rendre compte de la mesure dans laquelle le racisme, les divisions découlant de caractéristiques ethniques, linguistiques et nationales, de pair avec l’appartenance à une classe sociale, façonnent différemment les situations d’oppression fondée sur le sexe que subissent les femmes ainsi que leur résistance à cette oppression. Une des tâches fondamentales que le mouvement des femmes du Québec doit encore accomplir consiste à aborder la diversité du vécu des femmes et les divisions croissantes entre elles

"Permeating all community activities"? Comparing events and programming in Westminster and Tower Hamlets public libraries

A comparative study of events and programming in two London public library services, Westminster and Tower Hamlets, is reported. The two services offer the same proportion of 'engagement' programming. Tower Hamlets operates a novel service model, though one with long antecedents, integrating library, learning and cultural services. Its extensive programmes of educational and special events have led to a great increase in visitors, though not to a corresponding increase in use of core library services

Reconstruction of 400 GeV/c proton interactions with the SHiP-charm project

The SHiP-charm project was proposed to measure the associated charm production induced by 400 GeV/c protons in a thick target, including the contribution from cascade production. An optimisation run was performed in July 2018 at CERN SPS using a hybrid setup. The high resolution of nuclear emulsions acting as vertex detector was complemented by electronic detectors for kinematic measurements and muon identification. Here we present first results on the analysis of nuclear emulsions exposed in the 2018 run, which prove the capability of reconstructing proton interaction vertices in a harsh environment, where the signal is largely dominated by secondary particles produced in hadronic and electromagnetic showers within the lead target
