Systematic expansion of tunneling rates

Friday, April 26th, 2019
Speaker: Björn Garbrecht Technical University Munich
I will review the theory of tunneling in quantum mechanics and field theory to one-loop order. Then, I will address how to systematically go beyond this approximation in an expansion based on Green's functions. One phenomenological relevance of this is that a consistent calculation of the tunneling rate in the Standard Model and beyond requires a one-loop resummation. Finally, the standard Euclideanized calculation of tunneling rates is related to a derivation based on real-time amplitudes.
