Radiative Symmetry breaking, Cosmic Strings and Observable Gravity Waves in symmetric
Waqas Ahmed, Umer Zubair
We implement shifted hybrid inflation in the framework of supersymmetric GUT model which provides a natural solution to the monopole problem appearing in the…
Observable r, Gravitino Dark Matter, and Non-thermal Leptogenesis in No-Scale Supergravity
Waqas Ahmed, Muhammad Moosa, Shoaib Munir +1
We analyse the shifted hybrid inflation in a no-scale SU(5) model with supersymmetry, which naturally circumvents the monopole problem. The no-scale framework is derivable as the e…
Constraining the Cosmic Strings Gravitational Wave Spectra in No Scale Inflation with Viable Gravitino Dark matter and Non Thermal Leptogenesis
Waqas Ahmed, M. Junaid, Salah Nasri +1
We revisit the hybrid inflation model gauged by extension of the Minimal Supersymmetric Standard Model (MSSM) in a no-scale background. Considering a single predictive…
Smooth Hybrid Inflation with Low Reheat Temperature and Observable Gravity Waves in Super-GUT
Waqas Ahmed, Athanasios Karozas, George K. Leontaris +1
We realize smooth hybrid inflation in the framework of supersymmetric model which provides a natural solution to the monopole problem appearing…
