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

A search for long-lived charged particles reaching the muon spectrometer is performed using a data sample of 37 pb<sup>-1</sup> from pp collisions at √s = 7 TeV collected by the ATLAS detector at the LHC in 2010. No excess is observed above the estimated background. Stable τ˜ sleptons ar...

description A search for long-lived charged particles reaching the muon spectrometer is performed using a data sample of 37 pb<sup>-1</sup> from pp collisions at √s = 7 TeV collected by the ATLAS detector at the LHC in 2010. No excess is observed above the estimated background. Stable τ˜ sleptons are excluded at 95% CL up to a mass of 136 GeV, in GMSB models with N<sub>5</sub> = 3, m<sub>messenger</sub> = 250 TeV, sign (μ) = 1 and tan β = 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 g˜ -balls.
