P-wave Sommerfeld enhancement near threshold: a simplified approach
Carlos Henrique de Lima, Alberto Tonero, Andres Vasquez +1
The calculation of P-wave Sommerfeld enhancement in processes with unstable particles in the final state is known to be divergent. In a complete description, where resonant (on-she…
Computing the Effective Action with the Functional Renormalization Group
Alessandro Codello, Roberto Percacci, Leslaw Rachwal +1
The "exact" or "functional" renormalization group equation describes the renormalization group flow of the effective average action . The ordinary effective action can b…
A renormalization group improved computation of correlation functions in theories with non-trivial phase diagram
Alessandro Codello, Alberto Tonero
We present a simple and consistent way to compute correlation functions in interacting theories with non-trivial phase diagram. As an example we show how to consistently compute th…
