Search for new phenomena in events with three or more charged leptons in pp collisions at TeV with the ATLAS detector
(Journal of High Energy Physics, 2015)
A generic search for anomalous production of events with at least three charged leptons is presented. The data sample consists of pp collisions at TeV collected in 2012 by the ATLAS experiment at the CERN Large Hadron ...
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. ...
Search for long-lived neutral particles decaying into lepton jets in proton-proton collisions at root s=8 Tev with the ATLAS detector
(Journal of High Energy Physics, 2014)
Several models of physics beyond the Standard Model predict neutral particles that decay into final states consisting of collimated jets of light leptons and hadrons (so-called lepton jets). These particles can also be ...
Search for microscopic black holes and string balls in final states with leptons and jets with the ATLAS detector at root s=8 TeV
(Journal of High Energy Physics, 2014)
A search for an excess of events with multiple high transverse momentum objects including charged leptons and jets is presented, using 20.3 fb(-1) of proton-proton collision data recorded by the ATLAS detector at the Large ...
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 ...
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 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 ...
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 ...
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 ...
