The objective of this research was to determine the prevalence of retrospectively recalled childhood trauma among depressed patients and to examine the relationship between retrospective recall of childhood maltreatment and the onset, course, and severity of major depression in adulthood. Forty-seven adults with DSM-IV major depression and forty-one healthy(More)
Properties of the Higgs boson with mass near 125 GeV are measured in proton-proton collisions with the CMS experiment at the LHC. Comprehensive sets of production and decay measurements are combined. The decay channels include γ γ , ZZ, WW, τ τ , bb, and μμ pairs. The data samples were collected in 2011 and 2012 and correspond to integrated luminosities of(More)
A measurement is presented of differential cross sections for Higgs boson (H) production in pp collisions at √ s = 8 TeV. The analysis exploits the H → γ γ decay in data corresponding to an integrated luminosity of 19.7 fb −1 collected by the CMS experiment at the LHC. The cross section is measured as a function of the kinematic properties of the diphoton(More)
Measurements of the differential and double-differential Drell–Yan cross sections in the dielectron and dimuon channels are presented. They are based on proton– proton collision data at √ s = 8 TeV recorded with the CMS detector at the LHC and corresponding to an integrated luminosity of 19.7 fb −1. The measured inclusive cross section in the Z peak region(More)
New sets of parameters (" tunes ") for the underlying-event (UE) modelling of the pythia8, pythia6 and herwig++ Monte Carlo event generators are constructed using different parton distribution functions. Combined fits to CMS UE proton–proton (pp) data at √ s = 7 TeV and to UE proton–antiproton (pp) data from the CDF experiment at lower √ s, are used to(More)
A search for a standard model Higgs boson produced in association with a top-quark pair and decaying to bottom quarks is presented. Events with hadronic jets and one or two oppositely charged leptons are selected from a data sample corresponding to an integrated luminosity of 19.5 fb −1 collected by the CMS experiment at the LHC in pp collisions at a(More)
A search has been performed for long-lived particles that could have come to rest within the CMS detector, using the time intervals between LHC beam crossings. The existence of such particles could be deduced from observation of their decays via energy deposits in the CMS calorime-ter appearing at times that are well separated from any proton–proton(More)
Stringent limits are set on the long-lived lepton-like sector of the phenomenological minimal supersymmetric standard model (pMSSM) and the anomaly-mediated super-symmetry breaking (AMSB) model. The limits are derived from the results presented in a recent search for long-lived charged particles in proton–proton collisions, based on data collected by the(More)
