论文摘要
我讨论了$ b \ to d^{(*)} \ellν$形式的晶格计算中的最新进展,对于标准模型(SM)中$ | v_ {cb} | $的精确确定很重要,对于测试sm的sm期望在观察值$ r(d^{(*)}}})中。我还讨论了相关$ b \ to c $ emeptonic衰减的计算进度,$ b_s \ to d_s^{(*)} \ellν$和$ b_c \ to j/ψ\,\ellν$现在在LHC上可以实验访问。
I discuss recent progress in lattice calculations of $B \to D^{(*)} \ell ν$ form factors, important for the precision determination of $|V_{cb}|$ in the Standard Model (SM), and for testing SM expectations of lepton flavor universality in observables $R(D^{(*)})$. I also discuss progress in calculations of the related $b \to c$ semileptonic decays $B_s \to D_s^{(*)} \ell ν$ and $B_c \to J/ψ\, \ell ν$ now experimentally accessible at the LHC.
