Amelioration of Little Hierarchy Problem in SU(4)_c x SU(2)_L x SU(2)_R
Ilia Gogoladze, Mansoor Ur Rehman, Qaisar Shafi
The little hierarchy problem encountered in the constrained minimal supersymmetric model (CMSSM) can be ameliorated in supersymmetric models based on the gauge symmetry G_{422} \eq…
Type II Seesaw and the PAMELA/ATIC Signals
Ilia Gogoladze, Nobuchika Okada, Qaisar Shafi
We discuss how the cosmic ray signals reported by the PAMELA and ATIC/PPB-BETS experiments may be understood in a Standard Model (SM) framework supplemented by type II seesaw and a…
Yukawa Unification and Neutralino Dark Matter in SU(4)_c \times SU(2)_L \times SU(2)_R
Ilia Gogoladze, Rizwan Khalid, Qaisar Shafi
We consider a left-right symmetric SU(4)_c \times SU(2)_L \times SU(2)_R (4-2-2) model with gravity mediated supersymmetry breaking. We find that with 4-2-2 compatible non-universa…
Hybrid Inflation Revisited in Light of WMAP5
Mansoor Ur Rehman, Qaisar Shafi, Joshua R. Wickman
We study the effects of including one-loop radiative corrections in a non-supersymmetric hybrid inflationary model. These corrections can arise from Yukawa couplings between the in…
NMSSM and Seesaw Physics at LHC
Ilia Gogoladze, Nobuchika Okada, Qaisar Shafi
We consider extensions of the next-to-minimal supersymmetric model (NMSSM) in which the observed neutrino masses are described in terms of effective dimension six (or seven) rather…
A Realistic Radiative Fermion Mass Hierarchy in Non-supersymmetric SO(10)
S. M. Barr, Almas Khan
A non-supersymmetric grand unified theory can exhibit a "radiative fermion mass hierarchy", in which the heavier quarks and leptons get mass at tree level and the lighter ones get…
