Probing lepton flavor violation in meson decays with LHC data
Abstract
Abstract In this letter, we use LHC data from the Drell–Yan processes $$$$pp\rightarrow \ell _i\ell _j$$$$ (with $$$$i\ne j$$$$ ) to derive model-independent upper limits on lepton-flavor-violating meson decays. Our analysis is based on an Effective Field Theory (EFT) approach and it does not require a specific assumption regarding the basis of effective operators. We find that current LHC data (140 $$$$\textrm{fb}^{-1}$$$$ ) already provides competitive limits on $$$${\mathcal {B}}(B\rightarrow \pi e \tau )$$$$ and $$$${\mathcal {B}}(B\rightarrow \pi \mu \tau )$$$$ with respect to the ones obtained through experimental searches at the B -factories. Moreover, we derive upper limits on several decays that have not been searched for experimentally yet, such as $$$$D^0\rightarrow e\tau $$$$ in the charm sector, and various semileptonic decays such as $$$$B\rightarrow \rho \mu \tau $$$$ , $$$$B_s\rightarrow K \mu \tau $$$$ and $$$$B_s\rightarrow \phi \mu \tau $$$$ . Lastly, we discuss the validity of the EFT description of LHC data and the impact of loop corrections in our analysis.
