Description
The contributions of the charged axial-vector mesons b(1235) and a1(1270) as exchange particles in the decay mode K/sub S/→γγ are compared with those of the vector mesons p(770), ω(783), phi(1020), and psi(3097). The range of the rates of decay obtained for several choices of the cutoff mass falls within the limits of the value Γ(K/sub S/→2γ)Γ(K/sub S/→all) = (2.4 +- 1.2) x 10-6 obtained recently by the NA31 experimental group at the CERN SPS
