Search for neutral color-octet weak-triplet scalar particles in proton-proton collisions at root s=8TeV
(Journal of High Energy Physics, 2015)
A search for pair production of neutral color-octet weak-triplet scalar particles (Theta(0)) is performed in processes where one Theta(0) decays to a pair of b quark jets and the other to a Z boson plus a jet, with the Z ...
Measurement of the underlying event activity using charged-particle jets in proton-proton collisions at root s=2.76 TeV
(Journal of High Energy Physics, 2015)
A measurement of the underlying event (UE) activity in proton-proton collisions is performed using events with charged-particle jets produced in the central pseudorapidity region (vertical bar eta(jet) | LT 2) and with ...
Measurement of the ratio of the production cross sections times branching fractions of B-c(+/-) - GT J/psi pi(+/-) and B-+/- - GT J/psi K-+/- and B(B-c(+/-) - GT J/psi pi(+/-)pi(+/-)pi(-/+))/B(B-c(+/-) - GT J/psi pi(+/-)) in pp collisions at root s=7 Tev
(Journal of High Energy Physics, 2015)
The ratio of the production cross sections times branching fractions (sigma(B-c(+/-))B(B-c(+/-) - GT J/psi pi(+/-)))/(sigma(B-+/-)B(B-+/- - GT J/psi K-+/-)) is studied in proton-proton collisions at a center-of-mass energy ...
Measurement of the Z gamma production cross section in pp collisions at 8 TeV and search for anomalous triple gauge boson couplings
(Journal of High Energy Physics, 2015)
The cross section for the production of Z gamma in proton-proton collisions at 8 TeV is measured based on data collected by the CMS experiment at the LHC corresponding to an integrated luminosity of 19.5 fb(-1). Events ...
Search for production of vector-like quark pairs and of four top quarks in the lepton-plus-jets final state in pp collisions at root 8=8 TeV with the ATLAS detector
(Journal of High Energy Physics, 2015)
A search for pair production of vector-like quarks, both up-type (T) and down-type (B), as well as for four-top-quark production, is presented. The search is based on pp collisions at TeV recorded in 2012 with the ATLAS ...
Comparison of the Z/gamma* plus jets to gamma plus jets cross sections in pp collisions at root s=8 TeV
(Journal of High Energy Physics, 2015)
A comparison of the differential cross sections for the processes Z/gamma* + jets and photon (gamma)+ jets is presented. The measurements are based on data collected with the CMS detector at root s = 8TeV corresponding to ...
Measurement of charm and beauty production at central rapidity versus charged-particle multiplicity in proton-proton collisions at root s=7 TeV
(Journal of High Energy Physics, 2015)
Prompt D meson and non-prompt J/psi yields are studied as a function of the multiplicity of charged particles produced in inelastic proton-proton collisions at a centre-of-mass energy of root s = 7 TeV. The results are ...
Measurement of the forward-backward asymmetry of electron and muon pair-production in pp collisions at root s=7 TeV with the ATLAS detector
(Journal of High Energy Physics, 2015)
This paper presents measurements from the ATLAS experiment of the forward-backward asymmetry in the reaction pp - GT Z/gamma* - GT l(+)l(-), with l being electrons or muons, and the extraction of the effective weak mixing ...
Coherent rho(0) photoproduction in ultra-peripheral Pb-Pb collisions at root s(NN)=2.76 TeV
(Journal of High Energy Physics, 2015)
We report the first measurement at the LHC of coherent photoproduction of rho(0) mesons in ultra-peripheral Pb-Pb collisions. The invariant mass and transverse momentum distributions for rho(0) production are studied in ...
Search for the b(b)over-bar decay of the Standard Model Higgs boson in associated (W/Z)H production with the ATLAS detector
(Journal of High Energy Physics, 2015)
A search for the b (b) over bar decay of the Standard Model Higgs boson is performed with the ATLAS experiment using the full dataset recorded at the LHC in Run 1. The integrated luminosities used are 4.7 and 20.3 fb(-1) ...
