Thermal Relic Abundances of Particles with Velocity-Dependent Interactions
James B. Dent, Sourish Dutta, Robert J. Scherrer
We reexamine the evolution of thermal relic particle abundances for the case where the interaction rate depends on the particle velocities. For the case of Sommerfeld enhancement,…
Natural fermion mass hierarchy and mixings in family unification
James B. Dent, Robert Feger, Thomas W. Kephart +1
We present an SU(9) model of family unification with three light chiral families, and a natural hierarchy of charged fermion masses and mixings. The existence of singlet right hand…
Towards Realizing Warm Inflation in String Theory
Mar Bastero-Gil, Arjun Berera, James B. Dent +1
We give a generic argument that string theory provides a natural setting for warm inflationary cosmology. We then explore a specific model with an inflaton modulus field coupled to…
New Parametrization for the Scale Dependent Growth Function in General Relativity
James B. Dent, Sourish Dutta, Leandros Perivolaropoulos
We demonstrate the scale dependence of the growth function of cosmological perturbations in dark energy models based on General Relativity. This scale dependence is more prominent…
