Inclusive and differential W and Z at CMS and ATLAS

Several electroweak precision measurements are performed by the ATLAS and CMS collaborations at the LHC. The main ones are carried out using Drell-Yan production of single W and Z boson. They regard the measurement of the production cross sections of W and Z bosons, the mass of the W boson, and $\sin^2\theta_W$. The results of the $\sin^2\theta_W$ measurements have an accuracy of approximately twice that reached at LEP and SLD. Other measurements reported are about the Drell-Yan differential production cross section.Comment: Contribution to the 2019 QCD session of the 54th Rencontres de Morion

Measurement of Direct CP Asymmetries in Charmless Hadronic B Decays

Wage incentive profiles in dual labour markets

We propose a modified version of the Shapiro-Stiglitz’s (1984) efficiency wage model by introducing temporary contracts in the standard setup. New theoretical insights emerge on the incentive problem faced by workers and firms. We argue that the existence of temporary contracts broaden the incentive menu available to employers and that the optimal incentive structure can be sustained as an equi- librium outcome only if permanent contracts do not disappear. We also provide an alternative explanation of the wage penalty suffered by temporary workers even if standard models of efficiency wages would predict higher compensations for workers facing a higher job loss risk.Dual labour market, efficiency wages, wage differentials

Measurement of W and Z production in association with jets with CMS detector

We present a feasibility study of the Z and W boson production in association with jets with the first LHC data recorded by CMS detector with $pp$ collisions at $\sqrt{s}=10$ TeV

Searches for the standard model Higgs boson at CMS

We searched for the standard model Higgs boson using approximately 5 fb−1 of 7TeV pp collisions data collected with the CMS detector at LHC. We exclude at 95% confidence level a standard model Higgs boson with mass between 127.5 and 600 GeV. The expected 95% confidence level exclusion if the Higgs boson is not present is from 114.5 and 543GeV. The most significant excess is observed at 125 GeV with a local significance of 2.8σ. The excess is consistent both with background fluctuation and a standard model Higgs boson with mass of about 125 GeV

Measurement of angle beta with time-dependent CP asymmetry in B0->K+K-K0 decays

Einstein-Cartan pseudoscalaron inflation

We study a class of early universe cosmological models based on Einstein-Cartan gravity and including a higher derivative term corresponding to a power of the Holst scalar curvature. The resulting effective action is basically given by General Relativity and an additional neutral pseudoscalar field (the pseudoscalaron), unequivocally related to the corresponding components of the torsion, that necessarily acquire a dynamics. The induced pseudoscalaron potential provides a realistic inflationary phase together with a very rich postinflationary epoch, resulting by the coupling of the pseudoscalaron to ordinary matter.Comment: 18 pages, 7 figure

Not only a problem of fatigue and sleepiness: Changes in psychomotor performance in Italian nurses across 8-h rapidly rotating shifts

Although many studies have detailed the consequences of shift work in nurses concerning health, fatigue, sleepiness, or medical errors, no study has been carried out trying to disentangle the contribution of sleepiness and fatigue associated to shift work from the attentional performance. The aim of this pilot study is (A) to investigate the effects of an 8-h rapidly rotating shift on fatigue and sleepiness among staff nurses and (B) how these factors affect their psychomotor performance. Fourteen nurses were selected for a within-subject cross-sectional study according to this sequence of shifts: morning–afternoon–night, which were compared as function of tiredness, sleepiness, and performance at the Psychomotor Vigilance Task (PVT). Subsequently, a within-subject Analysis of Covariance (ANCOVA) evaluated if the observed differences between shifts persist when the contribution of sleepiness is controlled. Our results clearly indicate that night shifts are associated with significant greater sleepiness and tiredness, and worsened performance at the PVT. As hypothesized, ANCOVA showed that these differences disappear when the contribution of sleepiness is controlled. Results point to a lower psychomotor performance in night compared to day shifts that depends on sleepiness. Hence, interventions to minimize the consequences of the night shift should consider a reduction of sleepiness

The Data Quality Monitoring for the CMS Electromagnetic Calorimeter

The detector performance of the CMS electromagnetic calorimeter is monitored using applications based on the CMS Data Quality Monitoring (DQM) framework and running on the High-Level Trigger Farm as well as on local DAQ systems. The monitorable quantities are organized into hierarchical structures based on the physics content. The information produced is accessible by client applications according to their subscription requests. The client applications process the received quantities, according to pre-defined analyses, making the results immediately available, while also storing the results in a database, and in the form of static web pages, for subsequent studies. We describe here the functionalities of the CMS ECAL DQM applications and report about their use in real environments
