Search for heavy long-lived charged particles with the ATLAS detector in pp collisions ats=7TeV

Abstract

A search for long-lived charged particles reaching the muon spectrometer is performed using a data sample of 37 pb^-1 from pp collisions at sqrt(s) = 7 TeV collected by the ATLAS detector at the LHC. No excess is observed above the estimated background. Stable stau's are excluded at 95% CL up to a mass of 136 GeV, in GMSB models with N5 = 3, messenger = 250 TeV, sign(mu) = 1 and tan beta = 5. Electroweak production of sleptons is excluded up to a mass of 110 GeV. Gluino R-hadrons in a generic interaction model are excluded up to masses of 530 GeV to 544 GeV depending on the fraction of R-hadrons produced as gluino-balls9 pages plus author list (21 pages total), 4 figures, 4 tables, final version as it appears in Physics Letters B
