Right-hand currents and the Δ T = 1/2 rule in nonleptonic decays of strange particles
Vainshtein A.I., Zakharov V.I., Shifman M.A.
The influence of strong interaction at short distances on nonleptonic decays is calculated in models with right-hand bare currents. The contributions of the corresponding terms of the Hamiltonian Я(Д S = 1) to the matrix elements of the Κ—>2π decays is estimated.
