Measuring the top quark mass with the m(T2) variable

Abstract

We investigate the possibility of measuring the top quark mass using the collider variable m(T2) at the CERN LHC experiment. Monte Carlo studies of m(T2) are performed with the events corresponding to the dilepton decays of t (t) over bar produced at the LHC with 10 fb(-1) integrated luminosity. Our analysis suggests that the top quark mass can be determined by the m(T2) variable with a reasonable accuracy, though the precision will be determined by systematic errors for which a more complete analysis would need to be performed.
