论文摘要
在$ b $ -Meson衰减异常上的最新实验进度(特别是$ b \ to K^\astμμ$)上的动机,我们依靠一种简化的模型方法来研究媒介leptoquarks的前景,这些方法是在涉及多个风味的范围内允许多个有可能的衰变模式的探测器,可以允许(Inde)(Inde)(Indece)(Inde)(Inde)。我们的发现表明,确认$ b $ -Meson衰减异常,与积极信号(在Belle II或LHCB上)以$τ\至ϕμ $,$ b _ {(s)} $ - Meson衰减到$τ^+τ^+τ^ - $和$τ^+μ^ - $μ^ - $°^ - $°^^ - $ ther-usect Lepton违规腐烂(在彗星或MU2E上)将有助于加强这种情况的案例。我们还说明了$ r_ {d^{(*)}} $的实验确定的演变如何有助于通过v_1 $ v_1 $ leptoquark伪造对异常的$ b $ -b $ -meson衰减数据的解释。
Motivated by the recent experimental progress on the $B$-meson decay anomalies (in particular the angular observables in $B\to K^\astμμ$), we rely on a simplified-model approach to study the prospects of vector leptoquarks in what concerns numerous flavour observables, identifying several promising decay modes which would allow to (indirectly) probe such an extension. Our findings suggest that the confirmation of the $B$-meson decay anomalies, in parallel with positive signals (at Belle II or LHCb) for $τ\to ϕμ$, $B_{(s)}$-meson decays to $τ^+ τ^-$ and $τ^+ μ^-$ ($τ^+ e^-$) final states, as well as an observation of certain charged lepton flavour violation decays (at COMET or Mu2e), would contribute to strengthen the case for this scenario. We also illustrate how the evolution of the experimental determination of $R_{D^{(*)}}$ could be instrumental in falsifying an explanation of the anomalous $B$-meson decay data via a vector $V_1$ leptoquark.
