Query: Null-test signal for T-invariance violation in $pd$ scattering   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. the
$\rho$-meson, to the null-test observable $\widetilde\sigma$ is zero. The axial
$h_1$ meson exchange makes a non-zero contribution. We find that inclusion of
the Coulomb interaction does not lead to divergence of the cross section
$\widetilde\sigma$ and calculate its energy dependence at the proton beam
energy 100-1000 MeV.
