NLSP gluino and NLSP stop scenarios from b - tau Yukawa unification

摘要We present a study of the b - tau Yukawa unified supersymmetric SU(4)(c) x SU(2)(L) x SU(2)(R) model (with mu > 0), which predicts the existence of gluino-neutralino and stop-neutralino coannihilation scenarios compatible with the desired relic lightest supersymmetric particle neutralino dark matter abundance and other collider constraints. The next to lightest supersymmetric particle (NLSP) gluino or NLSP stop masses vary between 400 GeVand similar to 1 TeV. The NLSP gluinos will be accessible at the 14 TeV LHC, while we hope that the NSLP stop solutions will be probed in future LHC searches. We also identify regions of the parameter space in which the gluino and the lighter stop are closely degenerate in mass, interchangeably playing the role of NLSP and next to next to lightest supersymmetric particle (NNLSP). We also update a previous study of t - b - tau Yukawa unification and show that NLSP gluino of mass similar to 1 TeV, with a mass difference between the gluino and neutralino of less than 80 GeV, can be realized, consistent with the current collider and astrophysical constraints. We present benchmark points for b - tau and t - b - tau Yukawa unification that can be accessible at the LHC.
