Measuring Top Squark Interactions With The Standard Model Through Associated Production
arXiv:1105.1332 · doi:10.1103/PhysRevD.84.035015
Abstract
A new particle's interactions can be measured at colliders, by observing its associated production with Standard Model particles. We focus on the case of a collider-stable right-handed top squark and study the LHC sensitivities to its couplings to the photon, Z, and the Higgs boson. Such measurements determine the top squark's charge, mixing angle and coupling to the electroweak symmetry breaking sector. Determining these couplings can provide strong evidence for the supersymmetric solution to the hierarchy problem. Our analysis shows that the LHC has great prospects for measuring the photon and Higgs couplings, but will require a very high luminosity to measure the Z coupling.
