Precise LHC limits on the U_1 leptoquark parameter space

Parallel session talk Searches for New Physics T10: Searches for New Physics


Arvind Bhaskar (International Institute of information technology)


The $U_1$ leptoquark is the popular candidate to explain the persistent 𝐵-anomalies. In this talk, I will discuss the bounds which can be imposed on a $U_1$ leptoquark model using the latest LHC data. The current LHC data is quite sensitive towards the mass of $U_1$ and its couplings with the Standard Model second and third-generation fermions. 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 discuss how a TeV range $U_1$ can survive the LHC limits (from both dilepton and direct search data) and explain the anomalies. I will also point out some search channels for $U_1$.
