Diphoton resonances in a U(1)_{B-L} extension of the minimal supesymmetric standard model
G. Lazarides, Q. Shafi
Inspired by the 750 GeV diphoton state recently reported by ATLAS and CMS, we propose a U(1)_{B-L} extension of the MSSM which predicts the existence of four spin zero resonance st…
Minimal Supersymmetric
S. F. King, Q. Shafi
We present a minimal string-inspired supersymmetric model, and provide a detailed analysis of the symmetry breaking potential in this model, b…
Mu Problem and Hybrid Inflation in Supersymmetric SU(2)_L x SU(2)_R x U(1)_B-L
G. Dvali, G. Lazarides, Q. Shafi
We present a solution of the mu problem within a supersymmetric model based on the SU(2)_L x SU(2)_R x U(1)_{B-L} gauge group. We show that this solution implies a built-in hybrid…
New inflation, preinflation, and leptogenesis
V. N. Senoguz, Q. Shafi
We present a new inflation model in which the inflationary scenario including subsequent reheating is determined in part by a U(1)_R\times Z_n symmetry. A preinflation epoch can be…
A Predictive Inflationary Scenario Without The Gauge Singlet
G. Lazarides, Q. Shafi
We propose a new realization of the chaotic inflationary scenario in which the scalar field responsible for inflation also spontaneously breaks the underlying gauge symmetry at a s…
Supersymmetric Models With Tan(beta) Close to Unity
B. Ananthanarayan, K. S. Babu, Q. Shafi
Within the framework of supersymmetric grand unification, estimates of the quark mass based on the asymptotic relation single out the region with clo…
