摘要:

在单圈水平上研究了R宇称破坏的最小超对称标准模型对中子β衰变的贡献。结果表明,重子数和R宇称破坏相互作用通过单圈修正对D关联有贡献,而树级预测消失。通过考虑轻子数和R宇称破坏相互作用,在单圈水平上研究了Fierz干涉项。我们表明,未来的实验进展可以为我们提供更好的约束的一些组合的R-奇偶违反耦合。

英文摘要:

The contribution of the R-parity violating minimal supersymmetric standard model to the neutron beta decay at the one-loop level is investigated. It is found that the baryon number and R-parity violating interactions contribute to the D correlation through one-loop corrections, while the tree level prediction is vanishing. The Fierz interference term is also investigated at the one-loop level by considering the lepton number and R-parity violating interactions. We show that future experimental progress can provide us with better constraints on some of the combinations of R-parity violating couplings.
