Abstract

We discuss a model with a SU(2)_L doublet vector leptoquark (LQ), motivated by the recent experimental results relating to the lepton universality of B → D^(*) τν_τ. We find that scalar operators predicted by the LQ are favored to explain the deviations, taking into account the recent LHCb result. We investigate the extensive phenomenology of the model and conclude that B_s→ττ, B→ Kττ, B_u→ τ ν_τ and high-p_T di-τ lepton signatures at the LHC will probe the interesting parameter region in the near future.
