Successful reconstruction of neutralino masses at SPS1a point
Extension of DK method to two-body decay channels
Monte Carlo simulations confirm effectiveness
Abstract
Decay-frame Kinematics (DK) has previously been introduced as a technique to reconstruct neutralino masses from their three-body decays to leptons. This work is an extension to the case of two-body decays through on-shell sleptons, with Monte Carlo simulation of LHC collisions demonstrating reconstruction of neutralino masses for the SPS1a benchmark point.
