Meson structure in soft hadronic reactions at COMPASS
The measurement of the electric $(\alpha_{\pi})$ and magnetic $(\beta_{\pi})$ pion polarizabilities supplies a significant test of QCD predictions in particular in the framework of the chiral perturbation theory. In this perspective we have measured with the COMPASS spectrometer the t-dependence of...
