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.
