介质中λ β衰变

Lambda beta-decay in-medium

P. A. M. Guichon, A. W. Thomas

摘要:

在一个束缚强子的结构被它与其他强子的相互作用所改变的工作假设下,人们可以期望看到仔细选择的可观测量的变化。根据最近提出的测量束缚λ超子奇异度变化β衰变中轴向电荷的建议,我们研究了夸克-介子耦合模型中预期的变化大小。据预测,这将是重大的。

英文摘要:

Under the working hypothesis that the structure of a bound hadron is modified by its interactions with other hadrons, one may expect to see changes in carefully chosen observables. In the light of a recent proposal to measure the axial charge in the strangeness changing beta-decay of a bound Lambda hyperon, we examine the size of the change expected within the quark-meson coupling model. It is predicted to be significant.
