Resumen:
A search for highly ionising, penetrating particles with electric charges from |q|=2e|q|=2e to 6e is performed using the ATLAS detector at the CERN Large Hadron Collider. Protonproton collision data taken at s=7 TeV during the 2011 running period, corresponding to an integrated luminosity of 4.4 fb−14.4 fb−1,
are analysed. No signal candidates are observed, and 95% confidence
level cross-section upper limits are interpreted as mass-exclusion lower
limits for a simplified DrellYan production model. In this model,
masses are excluded from 50 GeV50 GeV up to 430, 480, 490, 470 and 420 GeV420 GeV for charges 2e, 3e, 4e, 5e and 6e, respectivel
