Estimating Vacuum Tunneling Rates
Indranil Dasgupta
We show that in Euclidean field theories that have bounce solutions, the bounce with the least action is the global minimum of the action in an open space of field configurations.…
Binary String Dynamics
Indranil Dasgupta, Ryan Rohm
In this paper we investigate the dynamical properties of binary cosmic strings. We find extrinsic curvature dependence of the string action and show that kinks on binary strings ar…
Vacuum Instability in Low-Energy Supersymmetry Breaking Models
Indranil Dasgupta, Bogdan A. Dobrescu, Lisa Randall
We show that for the simplest models of gauge mediated supersymmetry breaking, including all existing models, the true vacuum will not preserve QCD if it communicates supersymmetry…
Baryogenesis from Cosmic Strings at the Electroweak Scale
Indranil Dasgupta
We explore the viability of baryogenesis from light scalar decays after the electroweak phase transition. A minimal model of this kind is constructed with new CP violating interact…
