B强子的稀有衰变

Rare decays of B-hadrons

Carla Marin Benito

摘要:

b-强子的稀有衰变为新物理效应提供了高灵敏度。近年来,已经观察到了与标准模型预测的几个偏差,导致了全球拟合分析中的重大紧张局势。因此,更新现有的测量结果并研究新的衰变模式以确认这种模式至关重要。介绍了LHCb和Belle在辐射衰变、半轻子企鹅衰变、轻子普适性衰变和轻子味破坏衰变等方面的最新研究结果。

英文摘要:

Rare decays of b-hadrons provide high sensitivity to New Physics effects. Several deviations with respect to the Standard Model predictions have been observed in recent years, leading to significant tensions in global fit analyses. It is thus crucial to update the existing measurements and study new decay modes to confirm the pattern. The latest results from LHCb and Belle on radiative, semileptonic penguin, lepton universality and lepton flavour violation decays are presented.
