Title: Probing a simplified $W^{'}$ model of $R (D^{(*)})$ anomalies using $b$ tags, $τ$ leptons, and missing energy

Abstract

We study the LHC sensitivity to a W' produced via bottom and charm quarks and decaying to τ flavor leptons in the mass range 200–1000 GeV. We show that the extra b quarks necessitated by the production mechanism can improve the background rejection compared to an inclusive analysis relying solely on τ tagging and E $$miss\atop{T}$$ . We present prospective limits on the couplings and compare them to the best fit to the R (D^(*)) anomalies in B-meson decays.
