We look at anomalous interactions of the Wtb vertex. In case of the scenarios, when two of the four anomalous couplings can have non-SM values, we obtain constraints from three processes involving B-decays: Bd,s − B−d,s oscillations, the decay B → Xsγ and the decay B → Xsℓ+ℓ−. We only consider scenarios when two of the four anomalous couplings are allowed to have values different from thosein the Standard Model. We then compare our results with constraints from the t-channel single top quarkproduction cross section from , which were obtained for the same scenarios.
