Using top polarization for improving third generation squark searches
If supersymmetry is the solution to the Higgs mass hierarchy problem, this requires the existence of light stops and sbottoms. The current reach of the experimental searches for stops and sbottoms at the LHC is however still limited. In this work, we exploit the information about top polarization in sbottom (and stop) decays into tops, in order to gain better control over the signals arising from these sparticles. We discuss various scenarios leading to distinct top polarization. Further, we investigate different observables related to top polarization and comment upon their helpfulness to improve searches for third generation super-particles.
