Charged Pion-Pair Production and Pion Polarizabilities to two Loops
Urs Buergi
We evaluate the amplitude for gamma gamma --> pi^+ pi^- to two loops in the framework of chiral perturbation theory.The three new coupling constants that enter the result at this o…

Charged Pion Polarizabilities to two Loops
Urs Buergi
We evaluate the electric and magnetic polarizabilities of charged pions in the framework of chiral perturbation theory at next-to-leading order. This requires a two-loop evaluation…
