Oliver Witzel

AI总结:

本文回顾了重粲夸克和底夸克衰变中CKM矩阵元提取与味改变过程约束的理论进展,重点突出格点QCD计算的非微扰贡献。

摘要:

精确的实验测量与理论预言的结合,使得能够提取Cabibbo-Kobayashi-Maskawa(CKM)矩阵元,或在标准模型中约束味改变过程。聚焦于理论预言,我们回顾了重粲夸克和底夸克衰变领域的最新亮点。特别强调了利用格点QCD计算的、由强相互作用引起的非微扰贡献。

英文摘要:

The combination of precise experimental measurements and theoretical predictions allows to extract Cabibbo-Kobayashi-Maskawa (CKM) matrix elements or constrain flavor changing processes in the standard model. Focusing at theoretical predictions, we review recent highlights from the sector of heavy charm and bottom quark decays. Special emphasis is given to nonperturbative contributions due to the strong force calculated using lattice QCD.
