The authors' main claim 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 $\widetilde\sigma$ vanishes.

The integrated cross section $\widetilde\sigma$ 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 $\widetilde\sigma$ vanishes. Variation of the cross section $\widetilde\sigma$ due to strong hadronic and Coulomb interaction is studied and its energy dependence is calculated in the GeV region.

Original abstract
The integrated cross section $\widetilde\sigma$ 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 $\widetilde\sigma$ vanishes. Variation of the cross section $\widetilde\sigma$ due to strong hadronic and Coulomb interaction is studied and its energy dependence is calculated in the GeV region.

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.
