Abstract

In this paper, the decay of mesons have been studied by means of the Effective Hamiltonian Theory. Decay rates of the constituent S and quarks, in the tree and penguin levels are calculated via effective Lagrangian density of the weak interaction and then by using these obtained decay rates, the decay rates and branching ratios of K and are calculated and compared with the experimental results. Findings from this study are in a good agreement with the experimental values.
