Rare Kaon Decay K^+ --> \pi^+ u \bar{ u} in SU(3)_C X SU(3)_L X U(1)_N Models

摘要

The rare kaon decay K^+ --> \pi^+ \nu \bar{\nu} is considered in theframework of the models based on the SU(3)_C X SU(3)_L X U(1)_N (3 - 3 - 1)gauge group. It is shown that a lower bound of the Z' mass in the 3 - 3 - 1model with right-handed neutrinos at a value of 3 TeV is derived, while that inthe minimal version -- 1.7 TeV.
