Rare Kaon Decay K^+ --> π^+ ν\barν in SU(3)_C X SU(3)_L X U(1)_N Models

Hoang Ngoc Long, Le Phuoc Trung, Vo Thanh Van

The rare kaon decay K^+ --> π^+ ν\barν is considered in the framework 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…
