SUSY Bino Dark Matter with coannihilation and collider analysis

Abstract

The nature of Dark Matter has been at the forefront for some time for several High Energy Phenomenology studies that seek to test the validity of Beyond the Standard Model (BSM) theories. Under scrutiny, the null results for tests of supersymmetric theories has shifted some attention to non-minimal versions such as the Triplet-extended minimal supersymmetric standard model (TMSSM) which we consider in this work. The promising feature of a stable Dark Matter candidate and solutions to the Hierarchy problem still stands as the motivation to explore this model and the different Dark Matter scenarios it allows. In this work, we probe the properties of a Bino-type lightest supersymmetric particle (LSP) Dark Matter candidate with coannihilation scenarios to satisfy constraints from (g−2)_μ, Dark Matter, and collider experiments. We perform a parameter scan to determine new constraints on the LSP physical masses. An analysis of collider constraints show which signals are most sensitive to these scenarios leading to its eventual exclusion.
