Rare Kaon Decay K~+ → π~+νν-bar in SU(3)_C direct X SU(3)_L direct X U(1)_N Models

摘要

The rare kaon decay K~+ → π~+νν-bar is considered in the framework of models based on the SU(3)_C direct X SU(3)_L direct X U(1)_N (3-3-1) gauge group. In the 3-3-1 model with right-handed neutrinos, the lower bound of the Z' mass is derived at 3 TeV, and that in the minimal version, at 1.7 TeV.
