Test of time-reversal symmetry in the proton-deuteron scattering

Abstract

The integrated cross section $\tilde{\sigma }$ for a special type of double polarized proton-deuteron scattering constitutes a null test forvtime-invariance violating but P-parity conserving effects. Using the Glauber theory for the $pd$ elastic scattering and different types of phenomenological T-odd P-even NN-interactions we show that the contribution of the lowest mass meson exchange, i.e. the $\rho$-meson, to the null-test signal $\tilde{\sigma }$ vanishes. Variation of the cross section $\tilde{\sigma }$ due to strong hadronic and Coulomb interaction is studied and its energy dependence is calculated in the GeV region.
