GUTs and Exceptional Branes in F-theory - II: Experimental Predictions

We consider realizations of GUT models in F-theory. Adopting a bottom up approach, the assumption that the dynamics of the GUT model can in principle…

Instantons and SUSY breaking in F-theory

We study instanton contributions to the superpotential of local F-theory compactifications which could potentially be used to engineer models of dyna…

The imprint of the relative velocity between baryons and dark matter …

The post-recombination streaming of baryons through dark matter keeps baryons out of low mass (<10^6 solar masses) halos coherently on scales of a fe…

A direct approach to quantum tunneling

The decay rates of quasistable states in quantum field theories are usually calculated using instanton methods. Standard derivations of these methods…
