Resumen:
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 ps = 7 TeV collected by the ATLAS detector at the LHC in 2010. No excess is observed above the estimated background. Stable ˜ sleptons are excluded at 95% CL up to a mass of 136 GeV, in GMSB models with N5 = 3, mmessenger = 250 TeV, sign(μ) = 1 and tan = 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.
