Search for the direct production of charginos, neutralinos and staus in final states with at least two hadronically decaying taus and missing transverse momentum in pp collisions at root s=8 TeVwith the ATLAS detecto
(Journal of High Energy Physics, 2014)
Results of a search for the electroweak associated production of charginos and next-to-lightest neutralinos, pairs of charginos or pairs of tau sleptons are presented. These processes are characterised by final states with ...
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 ...
Search for neutral MSSM Higgs bosons decaying to a pair of tau leptons in pp collisions
(Journal of High Energy Physics, 2014)
A search for neutral Higgs bosons in the minimal supersymmetric extension of the standard model (MSSM) decaying to tau-lepton pairs in pp collisions is performed, using events recorded by the CMS experiment at the LHC. The ...
Search for the associated production of the Higgs boson with a top-quark pair
(Journal of High Energy Physics, 2014)
A search for the standard model Higgs boson produced in association with a top-quark pair (t (t) over barH) is presented, using data samples corresponding to integrated luminosities of up to 5.1 fb(-1) and 19.7 fb(-1) ...
Study of hadronic event-shape variables in multijet final states in pp collisions at root s=7 TeV
(Journal of High Energy Physics, 2014)
Event-shape variables, which are sensitive to perturbative and nonperturbative aspects of quantum chromodynamic (QCD) interactions, are studied in multijet events recorded in proton-proton collisions at root s = 7 TeV. ...
Searches for third-generation squark production in fully hadronic final states in proton-proton collisions at root s=8 TeV
(Journal of High Energy Physics, 2015)
Searches for third-generation squarks in fully hadronic final states are presented using data samples corresponding to integrated luminosities of 19.4 or 19.7 fb(-1), collected at a centre-of-mass energy of 8 TeV with the ...
Search for the production of dark matter in association with top-quark pairs in the single-lepton final state in proton-proton collisions at root s=8 TeV
(Journal of High Energy Physics, 2015)
A search is presented for particle dark matter produced in association with a pair of top quarks in pp collisions at a centre-of-mass energy of root s = 8TeV. The data were collected with the CMS detector at the LHC and ...
Measurement of the W boson helicity in events with a single reconstructed top quark in p p collisions at root s=8 TeV
(Journal of High Energy Physics, 2015)
A measurement of the W boson helicity is presented, where the W boson originates from the decay of a top quark produced in pp collisions. The event selection, optimized for reconstructing a single top quark in the final ...
Rapidity and transverse-momentum dependence of the inclusive J/psi nuclear modification factor in p-Pb collisions at root s(NN)=5.02 TeV
(Journal of High Energy Physics, 2015)
We have studied the transverse-momentum (p(T)) dependence of the inclusive J/psi production in p-Pb collisions at root s(NN) = 5.02 TeV, in three center-of-mass rapidity (y(cms)) regions, down to zero p(T). Results in the ...
Evidence for the Higgs-boson Yukawa coupling to tau leptons with the ATLAS detector
(Journal of High Energy Physics, 2015)
Results of a search for H - GT tau tau decays are presented, based on the full set of proton-proton collision data recorded by the ATLAS experiment at the LHC during 2011 and 2012. The data correspond to integrated ...
