Constraining Non-thermal and Thermal properties of Dark Matter
P. S. Bhupal Dev, Anupam Mazumdar, Saleh Qutub
We describe the evolution of Dark Matter (DM) abundance from the very onset of its creation from inflaton decay under the assumption of an instantaneous reheating. Based on the ini…
Quantifying the reheating temperature of the universe
Anupam Mazumdar, Bryan Zaldívar
The aim of this paper is to determine an exact definition of the reheat temperature for a generic perturbative decay of the inflaton. In order to estimate the reheat temperature, t…
Baryogenesis, dark matter and inflation in the Next-to-Minimal Supersymmetric Standard Model
Csaba Balazs, Anupam Mazumdar, Ernestas Pukartas +1
Explaining baryon asymmetry, dark matter and inflation are important elements of a successful theory that extends beyond the Standard Model of particle physics. In this paper we ex…
Inflationary buildup of a vector field condensate and its cosmological consequences
Juan C. Bueno Sanchez, Konstantinos Dimopoulos
Light vector fields during inflation obtain a superhorizon perturbation spectrum when their conformal invariance is appropriately broken. Such perturbations, by means of some suita…
An accurate bound on tensor-to-scalar ratio and the scale of inflation
Sayantan Choudhury, Anupam Mazumdar
In this paper we provide an accurate bound on primordial gravitational waves, i.e. tensor-to-scalar ratio for a general class of single-field models of inflation where inflat…
Low & High scale MSSM inflation, gravitational waves and constraints from Planck
Sayantan Choudhury, Anupam Mazumdar, Supratik Pal
In this paper we will analyze generic predictions of an inflection-point model of inflation with Hubble-induced corrections and study them in light of the Planck data. Typically in…
