Polarization effects in $\bar N+N \to \pi + \ell^{+} + \ell^{−}$ reaction. General analysis and numerical estimations
G.I. Gakh et al (E. Tomasi-Gustafsson)
A general formalism is developed to calculate the cross section and the polariza- tion observables for the reaction $\\bar N+N \\to \\pi + \\ell^{+} + \\ell^{−}$ . The matrix element and the observables are expressed in terms of six scalar amplitudes (complex functions of three kinematical variables) which determine the reaction dynamics. The numer- ical predictions are given in frame of a particular model in the kinematical range accessible in the PANDA experiment at FAIR.
