The possibility for a pion polarizability measurement at COMPASS
The pion electromagnetic structure can be probed in $\pi^{−}+(A,Z)\rightarrow\pi^{-}+(A,Z) + \gamma$ Compton scattering in inverse kinematics (Primakoff reaction) and described by the electric $(\alpha_{\pi})$ and the magnetic $(\beta_{\pi})$ polarizabilities that depend on the rigidity of pion’s i...
