Search for medium effects using jets from bottom quarks in PbPb collisions at $\sqrt{sNN}$ =5.02 TeV

A. Tumasyan, W. Adam, J. W. Andrejkovic, T. Bergauer et autres

The first study of the shapes of jets arising from bottom (b) quarks in heavy ion collisions is presented. Jet shapes are studied using charged hadron constituents as a function of their radial distance from the jet axis. Lead-lead (PbPb) collision data …

Azimuthal anisotropy of charged particles with transverse momentum up to 100 GeV/c in PbPb collisions at sNN=5.02 TeV

A. M. Sirunyan, A. Tumasyan, W. Adam, E. Asilar et autres

The Fourier coefficients v 2 and v 3 characterizing the anisotropy of the azimuthal distribution of charged particles produced in PbPb collisions at s NN = 5.02 TeV are measured with data collected by the CMS experiment. The measurements cover a broad …

Search for a Light Pseudoscalar Higgs Boson in the Dimuon Decay Channel in p p Collisions at s = 7 TeV

S. Chatrchyan, V. Khachatryan, A. M. Sirunyan, A. Tumasyan et autres

The dimuon invariant mass spectrum is searched in the range between 5.5 and 14 GeV for a light pseudoscalar Higgs boson $a$, predicted in a number of new physics models, including the next-to-minimal supersymmetric standard model. The data sample used in the …

Search for heavy Majorana neutrinos in μ±μ±+jets and e±e±+jets events in pp collisions at s=7 TeV

S. Chatrchyan, V. Khachatryan, A. M. Sirunyan, A. Tumasyan et autres

A search is performed for heavy Majorana neutrinos (N) using an event signature defined by two samesign charged leptons of the same flavour and two jets.The data correspond to an integrated luminosity of 4.98 fb -1 of pp collisions at a centre-of-mass …

Search for physics beyond the standard model in events with a Z boson, jets, and missing transverse energy in pp collisions at s=7 TeV

S. Chatrchyan, V. Khachatryan, A. M. Sirunyan, A. Tumasyan et autres

A search is presented for physics beyond the standard model (BSM) in events with a Z boson, jets, and missing transverse energy (E miss T ).This signature is motivated by BSM physics scenarios, including supersymmetry.The study is performed using a sample of …

Search for neutral Higgs bosons decaying to tau pairs in pp collisions at s=7 TeV

S. Chatrchyan, V. Khachatryan, A. M. Sirunyan, A. Tumasyan et autres

A search for neutral Higgs bosons decaying to tau pairs at a center-of-mass energy of 7 TeV is performed using a dataset corresponding to an integrated luminosity of 4.6 fb−1 recorded by the CMS experiment at the LHC. The search is sensitive …
