| Percentage timing efficiency as a function of gluino lifetime. The region 10−5 to 103seconds has the highest efficiency, approximately 37%. For shorter lifetimes many R-hadrons decay in paired bunch crossings while for longer lifetimes many decay when ATLAS is not taking data. The solid line is calculated with the assumption that no R-hadron survived from one run to the next (allowing a per run analysis for shorter lifetimes). The dashed line is calculated after averaging over bunch structure but does allow R-hadrons to decay in a run they are not produced in. |
