Gravitino Dark matter, Non Thermal Leptogenesis and Low reheating temperature in No-scale Higgs Inflation
Waqas Ahmed, Athanasios Karozas, George K. Leontaris
We revisit Higgs inflation in the framework of a minimal extension of the Standard Model gauge symmetry by a factor. Various aspects are taken into account with partic…
Sparticle Spectroscopy and Dark Matter in a extension of MSSM
Waqas Ahmed, Shabbar Raza, Qaisar Shafi +2
We consider a class of SUSY models in which the MSSM gauge group is supplemented with a gauged symmetry and a global symmetry. This extension introduces onl…
Helical phase inflation and its observational constraints
Mudassar Sabir, Waqas Ahmed, Yungui Gong +2
We consider a class of helical phase inflation models from the supergravity where the phase component of a complex field acts as an inflaton. This class of models…
The PeV-Scale Split Supersymmetry from Higgs Mass and Electroweak Vacuum Stability
Waqas Ahmed, Adeel Mansha, Tianjun Li +3
The null results of the LHC searches have put strong bounds on new physics scenario such as supersymmetry (SUSY). With the latest values of top quark mass and strong coupling, we s…
Inflation from a No-scale supersymmetric model
Waqas Ahmed, Athanasios Karozas
We study inflation in a supersymmetric Pati-Salam model driven by a potential generated in the context of no-scale supergravity. The Pati-Salam gauge group $SU(4)_{c}\times{SU(2)_{…
