On a possibility for a measurement of the transversal proton polarization in the diffractive pion production in pp and pe high energy collisions
Abstract
A mechanism of an asymmetry arising of the fragmentation products of a transversely polarized proton in processes of diffractive pion productions in pp and pe high energy collisions is considered. The asymmetry arises due to an interference of amplitudes, containing resonant state in the intermediate state pp yields pN* yields pN(pi), ep yields e(delta) yields eN(pi), with non-resonant background. The asymmetry has magnitude of tenths percents in the case of completely polarized proton, when the invariant mass of the (N(pi)) system is close to the resonant mass.
