Non-Universal Gaugino Masses and Natural Supersymmetry    [PDF]

Ilia Gogoladze, Fariha Nasir, Qaisar Shafi
We demonstrate that natural supersymmetry is readily realized in the framework of SU(4)_c \times SU(2)_L \times SU(2)_R with non-universal gaugino masses. Focusing on ameliorating the little hierarchy problem, we explore the parameter space of this model which yields small fine-tuning measuring parameters (natural supersymmetry) at the electroweak scale (\Delta_{EW}) as well as at high scale (\Delta_{HS}). It is possible to have both \Delta_{EW} and \Delta_{HS} less than 100 in these models, (2 % or better fine-tuning), while keeping the light CP-even (Standard Model-like) Higgs mass in the 123 GeV-127 GeV range. The light stop quark mass lies in the range 700 GeV View original: http://arxiv.org/abs/1212.2593
