Asymptotic Analysis of the Boltzmann Equation for Dark Matter Relics in the presence of a Running Dilaton and Space-Time Defects
Carl M. Bender, Nick E. Mavromatos, Sarben Sarkar
The interplay of dilatonic effects in dilaton cosmology and stochastic quantum space-time defects within the framework of string/brane cosmologies is examined. The Boltzmann equati…
CPT-Violating Leptogenesis induced by Gravitational Defects
Nick E. Mavromatos, Sarben Sarkar
We explore leptogenesis induced by the propagation of neutrinos in gravitational backgrounds that may occur in string theory. The first background is due to linear dilatons and the…
PT-symmetric interpretation of double-scaling
Carl M. Bender, Moshe Moshe, Sarben Sarkar
The conventional double-scaling limit of an O(N)-symmetric quartic quantum field theory is inconsistent because the critical coupling constant is negative. Thus, at the critical co…
Asymptotic Analysis of the Boltzmann Equation for Dark Matter Relics
Carl M. Bender, Sarben Sarkar
This paper presents an asymptotic analysis of the Boltzmann equations (Riccati differential equations) that describe the physics of thermal dark-matter-relic abundances. Two differ…
Condensate Structure of D-particle Induced Flavour Vacuum
Nick E. Mavromatos, Sarben Sarkar, Walter Tarantino
It is argued that four Fermi interactions induced by non-perturbative effects due to scattering of stringy matter from D-particles, D-instantons and more generally bulk gauge field…
