We study the effect of anomalous Wtb couplings on the B -> Xs gamma branching ratio. The considered couplings are introduced as parts of gauge-invariant dimension-six operators that are built out of the Standard Model fields only. One-loop contributions from the charged-current vertices are assumed to be of the same order as the tree-level flavour-changing neutral current ones. Bounds on the corresponding Wilson coefficients are derived.

  1. Dimension-Six Terms in the Standard Model Lagrangian

    hep-ph 2010-08 accept novelty 7.0

    Re-enumeration of dimension-six SM operators yields 59 independent terms (15+19+25) when baryon number is conserved, versus 80 previously.
