Description
The $U_1$ leptoquark is a suitable candidate to explain the persistent anomalies in the semileptonic decays of the $B$ meson. In this talk, I will discuss how we can use the LHC data to constrain the $U_1$ models. Since the LHC is sensitive towards the leptoquark couplings, rather than the Wilson coefficients, I will discuss some simple scenarios with different couplings that can contribute to the relevant operators and show that the LHC data either rule out or severely constrain these simple $U_1$ scenarios. I will also discuss how the limits can be drawn on scenarios with multiple nonzero couplings from the high-$P_T$ dilepton data. I will show how a TeV range $U_1$ can evade the dilepton limits and the direct search bounds and explain the anomalies.
