论文摘要
在本文中,我们介绍了$ \ bar b \ b \ d^{(*)} \ ell \ bar {x} $衰减的差分衰变分布,在低能量有效的野外理论框架中具有巨大的右手中微子衰减,并显示RH Neutrinos的巨大效果如何解释RH的巨大效果,可以解释远前置的差异差异的正面价值。 $ΔA_ {\ text {fb}} \ equiv a _ {\ text {fb}}^μ-a _ _ {\ text {fb}}^e $,试时从belle数据中推断出来。我们还对$ q^2 $依赖的角度可观察物进行预测,以激发未来的测量。
In this paper, we present the differential decay distributions for $\bar B \to D^{(*)} \ell \bar{X}$ decays with a massive right-handed neutrino in the low-energy effective field theory framework and show how the massive effects of the RH neutrinos can explain the positive value of the difference in forward-backward asymmetries, $ΔA_{\text{FB}}\equiv A_{\text{FB}}^μ-A_{\text{FB}}^e$, tentatively inferred from Belle data. We also make predictions for $q^2$ dependent angular observables to motivate future measurements.
