Null-test signal for T-invariance violation in $pd$ scattering

Understand

The integrated proton-deuteron cross section $\widetilde\sigma$ for the case of the incident proton vector polarization $p_y^p$ and tensor polarization $P_{xz}$ 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 $\widetilde\sigma$ within the Glauber theory of the double-polarized $pd$ scattering.
• Full spin dependence of the ordinary strong $pN$ 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.
