Boosting the t(t)over-bar charge asymmetry

We propose a kinematical enhancement of the t (t) over bar charge asymmetry at the LHC by selecting events with the t (t) over bar centre of mass frame highly boosted along the beam axis. This kinematical selection increases the asymmetries and their significance up to a factor of two in a rather model-independent fashion. Hence, it can be a perfect complement to enhance model discrimination at the LHC. (C) 2011 Elsevier B.V. All rights reserved.
