Calibration of the CMS hadron calorimeters using proton-proton collision data at root s=13 TeV

Methods are presented for calibrating the hadron calorimeter system of theCMSetector at the LHC. The hadron calorimeters of the CMS experiment are sampling calorimeters of brass and scintillator, and are in the form of one central detector and two endcaps. These calorimeters cover pseudorapidities vertical bar eta vertical bar ee data. The energy scale of the outer calorimeters has been determined with test beam data and is confirmed through data with high transverse momentum jets. In this paper, we present the details of the calibration methods and accuracy.Peer reviewe

Women\u27s perspectives on marriage and rights in Morocco: risk factors for forced and early marriage in the Marrakech region

Despite the introduction of the new Family Law, or Moudawana, in Morocco, effectively raising the minimum age for marriage, the number of girls being forced into wedlock is rising. This increase has been a source of concern from a women’s rights perspective. The present study explored women’s experiences and perspectives in relation to factors that contribute to the occurrence of child and forced marriage in Morocco. Using a participatory approach, focus-group discussions and in-depth interviews were held with women in both urban and rural settings in the greater Marrakech region. Overall, 125 women, between 18 and 69 years of age, participated in the study. Our findings highlight the need for more open dialogue between (grand)parents and children. Overall, the Moudawana is perceived as a considerable step forward for women’s rights, yet study findings show that current policy provisions are not effective in abolishing forced marriages. Findings point to the need for a redefinition of the role of organisations, women’s associations and other groups, with the recommendation that they focus their future efforts on awareness-raising among older generations and refrain from directly intervening in cases of forced marriage. Sensitisation efforts, including the use of popular media, are crucial to reach members of this older population group, where illiteracy remains widespread

Marriage and Migration: Moroccan Women’s Views on Partner Choice, Arranged and Forced Marriage in Belgium

With family reunification as one of the key routes to legally gain entry to the European Union, governments are introducing more stringent legislation to counter abuses such as forced marriages and marriages of convenience. This study explores Moroccan women’s views on partner choice, arranged and forced marriages to ascertain the impact of the migratory context. Moreover, it examined whether the diasporic experience affects the occurrence of forced marriage. Using a participatory approach, focus-group discussions and in-depth interviews were held with women from the Moroccan community in both urban and provincial settings in Flanders, Belgium. Our findings indicate a preference for a partner in Belgium. Religion as opposed to ethnicity emerges as the most important attribute in a partner. Furthermore, religion is also a progressive voice in opinions on forced marriage and the virginity norm. Although forced marriages are no longer a pressing issue among the youth of the Moroccan Belgian community, the immigration legislation and policies that aim to enhance integration and tackle forced marriage and marriages of convenience appear to effectively deter women from choosing a partner from Morocco. Overall, the diasporic experience and migration context do not give rise to an increase of forced marriage among the Moroccan community; yet, arranged marriage is prevalent, even though it is on the decline

Habitus de migrante: um conceito que visa captar o cotidiano dos atores em mobilidade espacial

A análise das populações em mobilidade espacial negligencia, com frequência, o poder da situação que elas atravessam. Apesar de suas diferenças estruturais, seus membros partilham, no cotidiano, o que a autora chamou de "habitus de migrante", uma segunda natureza que funciona como fonte dos recursos necessários à gestão do novo contexto. Esse conceito se baseia no conjunto das pesquisas qualitativas da autora sobre exilados, migrantes e estudantes no exterior, e em uma extensa literatura internacional sobre esses objetos. Seu status exploratório requer, no entanto, a elaboração de protocolos de pesquisa que possam colocar em evidência os mecanismos de mediação que permitam compreender as mudanças vividas por esses atores na diacronia.<br>The analysis of populations under spatial mobility often ignores the strength of the situation they live in. Despite of the structural differences that singularize them, the displacement situation leads those actors to share a number of characteristics in everyday life that the author has christened a "migrant'shabitus", a second nature that functions as a source of the resources needed to manage the new context. This concept, to which the author still gives an exploratory status, derives from the ethnographic research she has conducted on exiles, migrants and international students, as well as of an extended sociological literature on these groups; and intends to explain the changes these actors go under in a diachronic perspective

Strategies and performance of the CMS silicon tracker alignment during LHC Run 2

The strategies for and the performance of the CMS silicon tracking system alignment during the 2015–2018 data-taking period of the LHC are described. The alignment procedures during and after data taking are explained. Alignment scenarios are also derived for use in the simulation of the detector response. Systematic effects, related to intrinsic symmetries of the alignment task or to external constraints, are discussed and illustrated for different scenarios

Measurements of dose-rate effects in the radiation damage of plastic scintillator tiles using silicon photomultipliers

Measurements are presented of the reduction of signal output due to radiation damage for plastic scintillator tiles used in the hadron endcap (HE) calorimeter of the CMS detector. The tiles were exposed to particles produced in proton-proton (pp) collisions at the CERN LHC with a center-of-mass energy of 13 TeV, corresponding to a delivered luminosity of 50 fb$^{-1}$. The measurements are based on readout channels of the HE that were instrumented with silicon photomultipliers, and are derived using data from several sources: a laser calibration system, a movable radioactive source, as well as hadrons and muons produced in pp collisions. Results from several irradiation campaigns using $^{60}$Co sources are also discussed. The damage is presented as a function of dose rate. Within the range of these measurements, for a fixed dose the damage increases with decreasing dose rate

Measurements with silicon photomultipliers of dose-rate effects in the radiation damage of plastic scintillator tiles in the CMS hadron endcap calorimeter

International audienceMeasurements are presented of the reduction of signal output due to radiation damage for two types of plastic scintillator tiles used in the hadron endcap (HE) calorimeter of the CMS detector. The tiles were exposed to particles produced in proton-proton (pp) collisions at the CERN LHC with a center-of-mass energy of 13 TeV, corresponding to a delivered luminosity of 50 fb−1. The measurements are based on readout channels of the HE that were instrumented with silicon photomultipliers, and are derived using data from several sources: a laser calibration system, a movable radioactive source, as well as hadrons and muons produced in pp collisions. Results from several irradiation campaigns using 60Co sources are also discussed. The damage is presented as a function of dose rate. Within the range of these measurements, for a fixed dose the damage increases with decreasing dose rate
