Abstract
We employ a top-quark mass measurement technique in the dilepton channel with in situ jet energy scale calibration. Three variables having different jet energy scale dependences are used simultaneously to extract not only the top-quark mass but also the energy scale of the jet from a single likelihood fit. Monte Carlo studies with events corresponding to an integrated luminosity of 5fb -1 proton-proton collisions at the Large Hadron Collider √s=7TeV are performed. Our analysis suggests that the overall jet energy scale uncertainty can be significantly reduced and the top-quark mass can be determined with a precision of less than 1GeV/c2, including jet energy scale uncertainty, at the Large Hadron Collider. © 2012 American Physical Society.
