Mass measurement in boosted decay systems at hadron colliders

Abstract

We report a new possibility of using the $\mct2$ (Constransverse mass) variable for mass measurement in single step decay chains involving missing particles with moderate transverse momentum. We show that its experimental feasibility is enhanced compared to the corresponding $\mt2$-kink method. We apply this method to reconstruct a pair of chargino decay chains.
