$R_{D^{(*)}}$异常和LHC之间的相互作用

Interplay between the $R_{D^{(*)}}$ anomaly and the LHC

Syuhei Iguro

摘要:

当前$R_{D^{(*)}}=BR(\bar{B} \to D^{(*)}τ\barν)/BR(\bar{B}\to D^{(*)} \ell \barν)$中的差异,其中$\ell=e,\,μ$可能意味着已知粒子的质量约为TeV。因此,在大型强子对撞机上测试这些场景是很有动机的。由于差异的大小和基于有效场论的分析,可能的新物理候选者的种类是有限的。我们重点讨论了带电希格斯粒子和细夸克粒子的可能性,并讨论了对撞机物理。

英文摘要:

The current discrepancy in $R_{D^{(*)}}=BR(\bar{B} \to D^{(*)}τ\barν)/BR(\bar{B}\to D^{(*)} \ell \barν)$ where $\ell=e,\,μ$ may imply a know particle with the mass around the order of TeV. Therefore it is well motivated to test those scenarios at the large hadron collider. Thanks to the size of the discrepancy and the analysis based on the effective field theory, the variety of the possible new physics candidates is limited. We focus on the charged Higgs and leptoquark possibility and discuss the collider physics.
