Null-test signal for T-invariance violation in $pd$ scattering
Abstract
The integrated proton-deuteron cross section for the case of the incident proton vector polarization and tensor polarization of the deuteron target provides a null test signal for time-reversal invariance violating but P-parity conserving (TVPC) effects. We study the null-test observable within the Glauber theory of the double-polarized scattering. Full spin dependence of the ordinary strong scattering amplitudes and different types of the hypothetical TVPC pN-amplitudes are taken into account. We show that the contribution from the exchange of the lowest-mass meson allowed in the TVPC interaction, i.e. the -meson, to the null-test observable is zero. The axial meson exchange makes a non-zero contribution. We find that inclusion of the Coulomb interaction does not lead to divergence of the cross section and calculate its energy dependence at the proton beam energy 100-1000 MeV.
