Measurement of prompt J/psi pair production in pp collisions at root s = 7 Tev
(Journal of High Energy Physics, 2014)
Production of prompt J/psi meson pairs in proton-proton collisions at root s = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb(-1). The two ...
Search for massive resonances decaying into pairs of boosted bosons in semi-leptonic final states at root s=8 TeV
(Journal of High Energy Physics, 2014)
A search for new resonances decaying to WW, ZZ, or WZ is presented. Final states are considered in which one of the vector bosons decays leptonically and the other hadronically. Results are based on data corresponding to ...
Search for anomalous production of prompt same-sign lepton pairs and pair-produced doubly charged Higgs bosons with root s=8 TeV pp collisions using the ATLAS detector
(Journal of High Energy Physics, 2015)
A low-background inclusive search for new physics in events with same-sign dileptons is presented. The search uses proton-proton collisions corresponding to 20.3 fb(-1) of integrated luminosity taken in 2012 at a centre-of-mass ...
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 ...
Search for neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at root s=8 TeV with the ATLAS detector
(Journal of High Energy Physics, 2014)
A search for the neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is performed on data from proton-proton collisions at a centre-of-mass energy of 8 TeV collected ...
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 inclusive jet cross-section in proton-proton collisions at root s=7 TeV using 4.5 fb(-1) of data with the ATLAS detector
(Journal of High Energy Physics, 2015)
The inclusive jet cross-section is measured in proton-proton collisions at a centre-of-mass energy of 7 TeV using a data set corresponding to an integrated luminosity of 4.5 fb(-1) collected with the ATLAS detector at the ...
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) ...
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 ...
