Boosting the tt¯ charge asymmetry

We propose a kinematical enhancement of the tt¯ charge asymmetry at the LHC by selecting events with the tt¯ 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.
