In the name of truth: People’s reactions to ingroup and outgroup members who self-disclose a severe error

Usually people consider morality traits to be highly valuable, both in themselves and in others. Moreover, they tend to select moral groups and are often motivated to protect the positive identity of their groups by derogating immoral ingroup members. However, sometimes even moral ingroup members could represent a threat to the group and therefore be negatively evaluated, such as in the case of people who report another person’s wrongdoing (whistleblowing). To date an investigation of people’s judgments of someone who self- disclose his/her own wrongdoing is still missing. Our study aims to investigate how group members react to an ingroup and an outgroup member who confessed to having committed a severe wrongdoing. Results of a study conducted by using a real episode concerning a surgeon who confessed a fatal error, confirm our expectation; even if medical students appreciated the confession of the surgeon, they are less positive in evaluating his behavior compared to other student

Measurement of the Z boson differential cross section in transverse momentum and rapidity in proton-proton collisions at 8 TeV

We present a measurement of the Z boson differential cross section in rapidity and transverse momentum using a data sample of pp collision events at a centre-of-mass energy s=8 TeV, corresponding to an integrated luminosity of 19.7 fb-1. The Z boson is identified via its decay to a pair of muons. The measurement provides a precision test of quantum chromodynamics over a large region of phase space. In addition, due to the small experimental uncertainties in the measurement the data has the potential to constrain the gluon parton distribution function in the kinematic regime important for Higgs boson production via gluon fusion. The results agree with the next-to-next-to-leading-order predictions computed with the fewz program. The results are also compared to the commonly used leading-order MadGraph and next-to-leading-order powheg generators. © 2015 CERN for the benefit of the CMS Collaboration

Search for the associated production of the Higgs boson with a top-quark pair

A search for the standard model Higgs boson produced in association with a top-quark pair t t ¯ H (tt¯H) is presented, using data samples corresponding to integrated luminosities of up to 5.1 fb −1 and 19.7 fb −1 collected in pp collisions at center-of-mass energies of 7 TeV and 8 TeV respectively. The search is based on the following signatures of the Higgs boson decay: H → hadrons, H → photons, and H → leptons. The results are characterized by an observed t t ¯ H tt¯H signal strength relative to the standard model cross section, μ = σ/σ SM ,under the assumption that the Higgs boson decays as expected in the standard model. The best fit value is μ = 2.8 ± 1.0 for a Higgs boson mass of 125.6 GeV
