A decaying neutralino as dark matter and its gamma ray spectrum
Amin Aboubrahim, Tarek Ibrahim, Michael Klasen +1
It is shown that a decaying neutralino in a supergravity unified framework is a viable candidate for dark matter. Such a situation arises in the presence of a hidden sector with ul…
Xenon-1T excess as a possible signal of a sub-GeV hidden sector dark matter
Amin Aboubrahim, Michael Klasen, Pran Nath
We present a particle physics model to explain the observed enhancement in the Xenon-1T data at an electron recoil energy of 2.5 keV. The model is based on a extension of th…
Self-interacting hidden sector dark matter, small scale galaxy structure anomalies, and a dark force
Amin Aboubrahim, Wan-Zhe Feng, Pran Nath +1
The short distance behavior of dark matter (DM) at galaxy scales exhibits several features not explained by the typical cold dark matter (CDM) with velocity-independent cross-secti…
Corrections to Yukawa couplings from higher dimensional operators in a natural SUSY and HL-LHC implications
Amin Aboubrahim, Pran Nath, Raza M. Syed
We consider a class of unified models based on the gauge group which with appropriate choice of Higgs representations generate in a natural way a pair of light Hi…
Expanding the parameter space of natural supersymmetry
Amin Aboubrahim, Wan-Zhe Feng, Pran Nath
SUSY/SUGRA models with naturalness defined via small are constrained due to experiment on the relic density and the experimental limits on the WIMP-proton cross-section and WIM…
