Spectral tilt in A-term inflation
Rouzbeh Allahverdi, Anupam Mazumdar
Recently in hep-ph/0605035 and hep-ph/0608138, we have shown that primordial inflation can be embedded within the Minimal Supersymmetric Standard Model, while providing the right a…
Non-perturbative Gravity, Hagedorn Bounce & CMB
Tirthabir Biswas, Robert Brandenberger, Anupam Mazumdar +1
In hep-th/0508194 it was shown how non-perturbative corrections to gravity can resolve the big bang singularity, leading to a bouncing universe. Depending on the scale of the non-p…
Sub-eV Hubble scale inflation within gauge mediated supersymmetry breaking
Rouzbeh Allahverdi, Asko Jokinen, Anupam Mazumdar
Minimal Supersymmetric Standard Model with gauge mediated supersymmetry breaking has all the necessary ingredients for a successful sub-eV Hubble scale inflation $H_{\rm inf} \sim…
Longevity of supersymmetric flat directions
Rouzbeh Allahverdi, Anupam Mazumdar
We examine the fate of supersymmetric flat directions. We argue that the non-perturbative decay of the flat direction via preheating is an unlikely event. In order to address this…
Gauge invariant MSSM inflaton
Rouzbeh Allahverdi, Juan Garcia-Bellido, Kari Enqvist +1
We argue that all the necessary ingredients for successful inflation are present in the flat directions of the Minimally Supersymmetric Standard Model. We show that out of many gau…
Identifying the curvaton within MSSM
Rouzbeh Allahverdi, Kari Enqvist, Asko Jokinen +1
We consider inflaton couplings to MSSM flat directions and the thermalization of the inflaton decay products, taking into account gauge symmetry breaking due to flat direction cond…
