Description
In this talk, I will discuss how the pattern of chiral symmetry breaking can be utilzied to compute vector and axial-vector pion matrix elements in a uniform magnetic field. The results are constructed within chiral perturbation theory and therefore model independent for a magnetic field, $\sqrt{eB}$, weaker the typical hadronic scale of $4\pi F_{\pi}\sim 1\ \rm{GeV}$. The matrix elements determine the decay rate of both charged and neutral pions. We also compared our results with lattice QCD for which there is some tension.
