极化质子-氘核散射作为时间反演不变性的检验

Polarized proton-deuteron scattering as a test of time-reversal invariance

Yu. N. Uzikov, J. Haidenbauer

摘要:

具有横向极化$p_y^p$的质子在具有张量极化$P_{xz}$的氘核上的散射提供了时间反演(T)不变性破坏但宇称(P)守恒效应的零测试信号。在考虑T破坏P守恒核子-核子相互作用的自旋相关的Glauber理论中,我们计算了在束流能量100-1000 MeV处可观察到的相应的零检验。的S-波分量的氘核波函数以及D-波被考虑和后者被发现发挥重要作用的幅度和能量的可观察的问题。具体地,在包括D波的情况下,所获得的信号的最大值被移位到更高的射束能量,即700-800 MeV。

英文摘要:

Scattering of protons with transversal polarization $p_y^p$ on deuterons with tensor polarization $P_{xz}$ provides a null-test signal for time-reversal (T) invariance violating but parity (P) conserving effects. We calculate the corresponding null-test observable at beam energies 100-1000 MeV within the spin-dependent Glauber theory considering T-violating P-conserving nucleon-nucleon interactions. The S-wave component of the deuteron wave function as well as the D-wave are taken into account and the latter is found to play an important role for the magnitude and the energy dependence of the observable in question. Specifically, with inclusion of the D wave the maximum of the obtained signal is shifted to higher beam energies, i.e. to 700-800 MeV.
