Abstract
We perform an analysis on the polarization in the radiative transition and propose to use it to probe the mechanism of decay to the baryon-antibaryon pairs in experiment. To start with the unpolarized collisions, we follow the polarization transfer to the states, and estimate the degree of polarization. We show that the pair has rich spin configurations, which are beneficial for us to study its decay asymmetry parameter and measure the helicity amplitudes. The experimental observables to reveal the and spin polarization are presented.
