辐射$B$衰变对新物理的限制

Constraints on new physics from radiative $B$ decays

Ayan Paul, David M. Straub

摘要:

在$b \to s$跃迁中测量辐射衰变模式的新阶段已经开始,LHCb和Belle-II在包容性和排他性通道中显示出独特的承诺。在严格审查的强子不确定性的排他性辐射衰变,我们分析了最近的测量的分支比和质量本征态率不对称的$B_s\toϕγ$和$B\to K^*e^+e^-$在低$q^2$的角分布的影响,新的物理在$b\to sγ$过渡。

英文摘要:

A new phase for the measurements of radiative decay modes in $b \to s$ transitions has started with new measurements of exclusive modes by LHCb and with Belle-II showing distinctive promises in both inclusive and exclusive channels. After critically reviewing the hadronic uncertainties in exclusive radiative decays, we analyze the impact of recent measurements of the branching ratio and mass-eigenstate rate asymmetry in $B_s\toϕγ$ and of the angular distribution of $B\to K^*e^+e^-$ at low $q^2$ on new physics in the $b\to sγ$ transition.
