Scattering of protons with transversal polarization Pyp on deuterons with tensor polarization Pxz provides a null-test signal for time reversal invariance violating but P-parity conserving effects. The dedicated experiment will be done at COSY facility at proton beam energy 135 MeV using internal deuteron target. I give a brief review of results of theoretical calculations of the null... https://www.sneakerpoliticers.shop/product-category/bags/
