NLSP Gluino Search at the Tevatron and early LHC
M. Adeel Ajaib, Tong Li, Qaisar Shafi +1
We investigate the collider phenomenology of gluino-bino co-annihilation scenario both at the Tevatron and 7 TeV LHC. This scenario can be realized, for example, in a class of real…
Direct and Indirect Detection and LHC Signals of Bino-Higgsino Dark Matter
Ilia Gogoladze, Rizwan Khalid, Yukihiro Mimura +1
If the lightest dark matter neutralino has a sufficiently large Higgsino component, its spin-independent and spin-dependent cross sections on nucleons can be sizable enough to be d…
Observable Gravity Waves from Supersymmetric Hybrid Inflation II
Mansoor Ur Rehman, Qaisar Shafi, Joshua R. Wickman
It is shown that a tensor-to-scalar ratio close to r = 0.03, which can be observed by Planck, is realized in supersymmetric hybrid inflation models with TeV-scale soft supersymmetr…
Inflation in Supersymmetric SU(5)
S. Khalil, M. U. Rehman, Q. Shafi +1
We analyze the adjoint field inflation in supersymmetric (SUSY) SU(5) model. In minimal SUSY SU(5) hybrid inflation monopoles are produced at the end of inflation. We therefore exp…
Higgs Boson Mass Bounds in Seesaw Extended Standard Model with Non-Minimal Gravitational Coupling
Bin He, Nobuchika Okada, Qaisar Shafi
In the presence of non-minimal gravitational coupling between the standard model (SM) Higgs doublet and the curvature scalar , the effective…
Observable Gravity Waves From Supersymmetric Hybrid Inflation
Qaisar Shafi, Joshua R. Wickman
We identify models of supersymmetric hybrid inflation in which the tensor-to-scalar ratio, a canonical measure of gravity waves produced during inflation, can be as large as 0.03 o…
