我们分析了两种宇称非守恒的能量依赖关系 (PNC)在反应$\gamma D\到np$在近阈值区域的不对称性。第一个是与圆偏振光子束和非偏振氘核靶反应的不对称性。第二种对应于非偏振光子束和偏振目标。我们发现这两种不对称性对能量的依赖性有很大的不同,而且它们的形状对PNC-介子交换耦合常数很敏感。 预测未来可能的实验,以提供明确的约束的PNC耦合常数进行了讨论。
We analyze the energy dependence for two types of parity-non-conserving (PNC) asymmetries in the reaction $\gamma D\to np$ in the near-threshold region. The first one is the asymmetry in reaction with circularly polarized photon beam and unpolarized deuteron target. The second one corresponds to those with an unpolarized photon beam and polarized target. We find that the two asymmetries have quite different energy dependence, and their shapes are sensitive to the PNC-meson exchange coupling constants. The predictions for the future possible experiments to provide definite constraints for the PNC-coupling constants are discussed.
