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
Exploring compressed supersymmetry with same-sign top quarks at the CERN Large Hadron Collider
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
Cosmology of the DFSZ axino
We study the cosmological impact of the supersymmetric DFSZ axion model. Extending recent works, we first provide a comprehensive analysis of thermal production of the DFSZ axino considering all the

The MSSM with heavy scalars
We perform a comprehensive analysis of the Minimal Supersymmetric Standard Model (MSSM) in the scenario where the scalar partners of the fermions and the Higgs particles (except for the
Peccei-Quinn NMSSM in the light of 125 GeV Higgs
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


Exploring the BWCA (Bino-Wino co-annihilation) scenario for neutralino dark matter
In supersymmetric models with non-universal gaugino masses, it is possible to have opposite-sign SU(2) and U(1) gaugino mass terms. In these models, the gaugino eigenstates experience little mixing
Mixed wino dark matter: Consequences for direct, indirect and collider detection
In supersymmetric models with gravity-mediated SUSY breaking and gaugino mass unification, the predicted relic abundance of neutralinos usually exceeds the strict limits imposed by the WMAP
Mixed Higgsino dark matter from a reduced SU(3) gaugino mass: Consequences for dark matter and collider searches
In gravity-mediated SUSY breaking models with non-universal gaugino masses, lowering the SU(3) gaugino mass |M3| leads to a reduction in the squark and gluino masses. Lower third generation squark
Neutralino dark matter in mirage mediation
We study the phenomenology of neutralino dark matter (DM) in a mirage mediation scenario of supersymmetry breaking which results from the moduli stabilization in some string/brane models. Depending
Supersymmetric Dark Matter
A review of supersymmetric dark matter in minimal supergravity unification with R-parity invariance and with radiative breaking of the electro-weak symmetry is given. The analysis shows the lightest
The role of Wino content in neutralino dark matter
We investigate the dark matter prospects of supersymmetric models with nonuniversal gaugino masses at low values of tan{beta}. We find that for particular values of the ratio of soft
Relic neutralino densities and detection rates with nonuniversal gaugino masses
We extend previous analyses of the interplay between nonuniversalities in the gaugino mass sector and the thermal relic densities of LSP neutralinos, in particular to the case of moderate to large
Deflected anomaly mediation and neutralino dark matter
This is a study of the phenomenology of the neutralino dark matter in the so called deflected anomaly mediation scenario. This scheme is obtained from the minimal anomaly-mediated scenario by
Mediation of supersymmetry breaking in gauge messenger models
We study gauge mediation of supersymmetry breaking in SU(5) supersymmetric grand unified theory with gauge fields as messengers. The generated soft supersymmetry breaking parameters lead to close to
