Time-Reversal Invariance Violation Effect in dd Scattering / M.N.Platonova, Yu.N.Uzikov // Chinese Physics C [Electronic resource]. – 2025. – Vol. 49, No. 3. – P. 034108. – URL: https://doi.org/10.1088/1674-1137/ad9b9f.

A formalism is developed for calculating the signal of the violation of time-reversal invariance, provided that space-reflection (parity) invariance is conserved during the scattering of tensor-polarized deuterons on vector-polarized deuterons. The formalism is based on Glauber theory and fully considers the spin dependence of elastic scattering amplitudes and the spin structure of colliding deuterons. Numerical calculations are performed in the laboratory proton energy range T&sub(p)=0.1–1.2 GeV using the SAID database for spin amplitudes and in the energy region of the SPD NICA experiment corresponding to the invariant mass of the interacting nucleon pairs *%s&sub(NN)=2.5-25 GeV, using two phenomenological models of elastic scattering. It is found that only one type of the time-reversal non-invariant parity conserving interaction gives a non-zero contribution to the signal in question, which is important for isolating an unknown constant of this interaction from the corresponding data.
