Search for a standard model Higgs boson produced in association with a top-quark pair and decaying to bottom quarks using a matrix element method
(Springer, 2015)
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 ...
Production of leading charged particles and leading charged-particle jets at small transverse momenta in pp collisions at root s=8 TeV
(Amer Physical Soc, 2015)
The per-event yield of the highest transverse momentum charged particle and charged-particle jet, integrated above a given p(T)(min) threshold starting at p(T)(min) = 0.8 and 1 GeV, respectively, is studied in pp collisions ...
Study of final-state radiation in decays of Z bosons produced in pp collisions at 7 TeV
(Amer Physical Soc, 2015)
The differential cross sections for the production of photons in Z -> mu(+)mu(-)gamma decays are presented as a function of the transverse energy of the photon and its separation from the nearest muon. The data for these ...
Constraints on the pMSSM, AMSB model and on other models from the search for long-lived charged particles in proton-proton collisions at root s=8TeV
(Springer, 2015)
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 ...
Measurement of J/psi and psi(2S) Prompt Double-Differential Cross Sections in pp Collisions at root s=7 TeV
(Amer Physical Soc, 2015)
The double-differential cross sections of promptly produced J/psi and psi(2S) mesons are measured in pp collisions at root s = 7 TeV, as a function of transverse momentum p(T) and absolute rapidity \y\. The analysis uses ...
Search for resonances and quantum black holes using dijet mass spectra in proton-proton collisions at root s=8 TeV
(Amer Physical Soc, 2015)
A search for resonances and quantum black holes is performed using the dijet mass spectra measured in proton-proton collisions at root s = 8 TeV with the CMS detector at the LHC. The data set corresponds to an integrated ...
Evidence for Collective Multiparticle Correlations in p-Pb Collisions
(Amer Physical Soc, 2015)
The second-order azimuthal anisotropy Fourier harmonics, nu(2), are obtained in p-Pb and PbPb collisions over a wide pseudorapidity (.) range based on correlations among six or more charged particles. The p-Pb data, ...
Measurement of the ratio B(B-s(0) -> J/psi f(0)(980))/B(B-s(0) -> J/psi phi(1020)) in pp collisions at root s=7 TeV
(Elsevier, 2016)
A measurement of the ratio of the branching fractions of the B-s(0) meson to J/psi f(0)(980) and to J/psi phi(1020) is presented. The J/psi, f(0)(980), and phi(1020) are observed through their decays to mu(+)mu(-), pi(+)pi(-), ...
Precise determination of the mass of the Higgs boson and tests of compatibility of its couplings with the standard model predictions using proton collisions at 7 and 8 TeV
(Springer, 2015)
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 ...
