Search for heavy long-lived multi-charged particles in pp collisions at ... formula ... TeV using the ATLAS detector

摘要

A search for heavy long-lived multi-charged particles is performed using the ATLAS detector at the LHC. Data collected in 2012 at s=8 TeV from pp collisions corresponding to an integrated luminosity of 20.3 fb^-1are examined. Particles producing anomalously high ionisation, consistent with long-lived massive particles with electric charges from |q| = 2e to |q| = 6e are searched for. No signal candidate events are observed, and 95 % confidence level cross-section upper limits are interpreted as lower mass limits for a Drell–Yan production model. The mass limits range between 660 and 785 GeV.
