Techniques and Prospects for light-flavored sQuark Mass Measurements at a Multi-TeV e+e− Collider

A multi-TeV linear e+e− collider is an ideal tool for precise studies of squark masses. In scenarios where the gluino is heavier than the squarks, light-flavored right-squarks will decay almost exclusively into the corresponding quark and the lightest neutralino, leading to simple event topologies which offer excellent possibilities for clean mass measurements. We discuss three different techniques for the squark mass measurement and evaluate their performance at the 3 TeV CLIC e+e− collider in a generator-level study, highlighting the influence of initial state radiation and the beam energy spread due to beamstrahlung on the observed distributions. For 500 fb−1, resulting in about 2200 accepted events in the SPS1b scenario, statistical uncertainties of 3 GeV (0.35%) on the squark mass seem achievable.
