Almost degenerate bino and wino masses at the weak scale constitute one of the unique features of gauge messenger models. The lightest neutralino is a mixture of bino, wino and higgsino and can produce the correct amount of dark matter density if it is the lightest supersymmetric particle. Furthermore, as a result of the squeezed spectrum of superpartners which is typical for gauge messenger models, various co-annihilation and resonance regions overlap and very often the correct amount of…

Compressed supersymmetry and natural neutralino dark matter from top squark-mediated annihilation to top quarks
The parameters of the minimal supersymmetric standard model appear to require uncomfortably precise adjustment in order to reconcile the electroweak symmetry breaking scale with the lower mass limits
Top-squark-mediated annihilation scenario and direct detection of dark matter in compressed supersymmetry
Top-squark-mediated annihilation of b-ino-like neutralinos to top-antitop pairs can play the dominant role in obtaining a thermal relic dark matter abundance in agreement with observations. In a
TeV scale partial mirage unification and neutralino dark matter
We study the TeV scale partial mirage unification scenario, where the gluino and wino masses are degenerate around a TeV scale, but the bino mass is not degenerate. This scenario has

In compressed supersymmetry, a light top squark naturally mediates efficient neutralino pair annihilation to govern the thermal relic abundance of dark matter. I study the CERN LHC signal of
Implications of compressed supersymmetry for collider and dark matter searches
Martin has proposed a scenario dubbed ``compressed supersymmetry'' (SUSY) where the MSSM is the effective field theory between energy scales Mweak and MGUT, but with the GUT scale SU(3) gaugino mass

A bstractWe study the phenomenology of the Peccei-Quinn invariant extension of the next-to-minimal supersymmetric standard model (NMSSM) in view of the recent discovery of a 125 GeV Higgs boson. The
Moduli stabilization and supersymmetry breaking in deflected mirage mediation
We present a model of supersymmetry breaking in which the contributions from gravity/modulus, anomaly, and gauge mediation are all comparable. We term this scenario ``deflected mirage mediation'',

Exploring the BWCA (Bino-Wino co-annihilation) scenario for neutralino dark matter
