Measurement of the pion polarizabilities at COMPASS
The electromagnetic structure of pions is probed in $\pi\gamma$ Compton scattering in inverse kinematics (Primakoff effect) and described by the electric ($\alpha_{\pi}$) and magnetic ($\beta_{\pi}$) polarizabilities, that depend on the rigidity of pion’s internal structure as a composite particle....
