Radiative Rare Decay of Kaons

Abstract

The parity conserving (PC) and the parity violating (PV) coupling constants are evaluated by considering the PC and PV poles and these coupling constants are respectively given by: C = 1.12 × 10 −7 and D = 1.15 × 10 −7 . Using these coupling constants we have estimated the decay width of K 0 1 → π + π − γ and K 0 2 → π + π − π 0 γ. Our estimated decay width of K 0 1 → π + π − γ is in good agreement with the recent experimental result.
