摘要

Rare decay processes K+→π+v(v) and KL →π0v(v) are considered in the framework of three-site Higgsless model.The contributions of this new physics model to these two decay processes come from the new heavy gauge bosons and the correction terms for the couplings of the ordinary gauge bosons with fermions.Our numerical results show that the branching ratios of these two decay processes can be enhanced by 40% and 50% relative to those predicted by the standard model.
