Anomalous triple gauge couplings from $B$-meson and kaon observables

Abstract

We consider the three CP-conserving dimension-6 operators that encode the leading new-physics effects in the triple gauge couplings. The contributions to the standard-model electromagnetic dipole and semi-leptonic vector and axial-vector interactions that arise from the insertions of these operators are calculated. We show that radiative and rare $B$-meson decays provide, under certain assumptions, constraints on two out of the three anomalous couplings that are competitive with the restrictions obtained from LEP II, Tevatron and LHC data. The constraints arising from the $Z\to b\bar{b}$ electroweak pseudo observables, $K\to \pi \nu \bar{\nu }$ and ${\epsilon }^{\prime }/\epsilon$ are also studied.
