Abstract: In the Minimal Supersymmetric Extension of the Standard Model (MSSM) the higgsino mass parameter μ appears both in the masses of the Higgs bosons and in the neutralino mass matrix. Electroweak finetuning therefore prefers small… read more here.

DOI: 10.1103/physrevlett.124.121803
Abstract: Supersymmetric twin Higgs models have a discrete symmetry for which each standard model particle and its supersymmetric partner have a corresponding state that transforms under a mirror standard model gauge group. This framework is able… read more here.

DOI: 10.1142/s0217751x17500130
Abstract: The possibility of heavy neutralino dark matter (DM) in the gravity-mediation mechanism is explored. The appearance of the heavy lightest supersymmetric particle is seemingly suggested by Large Hadron Collider runs, which have not provided evidence… read more here.
