Title: | Search for heavy long-lived multi-charged particles in pp collisions at √s = 8 TeV using the ATLAS detector | Authors: | Santos, S. P. Amor dos Carvalho, J. Fiolhais, M. C. N. Galhardo, B. Veloso, F. Wolters, H. ATLAS Collaboration |
Issue Date: | 2015 | Publisher: | Springer Nature | Serial title, monograph or event: | European Physical Journal C | Volume: | 75 | Issue: | 8 | Abstract: | A search for heavy long-lived multi-charged particles is performed using the ATLAS detector at the LHC. Data collected in 2012 at√s = 8TeV from pp collisions corresponding to an integrated luminosity of 20.3 fb-1 are examined. Particles producing anomalously high ionisation, consistent with long-livedmassive particleswith electric charges from |q| = 2e to |q| = 6e are searched for. No signal candidate events are observed, and 95% confidence level crosssection upper limits are interpreted as lower mass limits for a Drell-Yan productionmodel. The mass limits range between 660 and 785 GeV. | URI: | https://hdl.handle.net/10316/109121 | DOI: | 10.1140/epjc/s10052-015-3534-2 | Rights: | openAccess |
