Triple gauge boson couplings in rareBandKdecays

We examine the sensitivity of flavor changing neutral current (FCNC) processes to anomalous triple gauge boson couplings. We show that in the non-linear realization of the electroweak symmetry breaking sector, these processes are very sensitive to two $\mathrm{CP}$ conserving anomalous couplings. A clean separation of their effects is possible in the next round of experiments probing $\overrightarrow{b}s\gamma$ and $\overrightarrow{b}s{\mathcal{l}}^{+}{\mathcal{l}}^{-}$ processes, as well as kaon decays such as $K^{+}\to {\pi }^{+}\nu \overline{\nu }.$ The obtained sensitivity is found to be competitive with that of direct measurements at high energy colliders. In particular, for one of the $\mathrm{WWZ}$ couplings the one-loop FCNC effects are enhanced by a logarithmic dependence on the scale of new physics. We also explore the potential signals of $\mathrm{CP}$ violating anomalous triple gauge boson couplings in rare $B$ decays.
