Spin observables of pd scattering and a null-test of T-invarinace violation

Abstract

Time-reversal invariance violating but P-parity conserving (TVPC) effects will be tested at COSY in proton-deuteron scattering at 135 MeV. A null-test signal for these effects provides an integrated cross section for vector polarized proton and tensor polarized deuteron. We use the Glauber theory with accounting for full spin-dependence of the proton-nucleon scattering amplitudes to calculate spin observables of pd elastic scattering. The obtained results are in reasonable agreement with existing data at energies 100-250 MeV. This provides a theoretical basis for estimation of TVPC effects and possible false signals in the planned pd scattering experiment.
