Including electromagnetism in K → ππ decay calculations
Because of the small size of the ratio A2/A0 of the I = 2 to I = 0 K → ππ decay amplitudes (the ΔI = 1/2 rule) the effects of electromagnetism on A2 may be a factor of 20 larger than given by a naive O(±EM) estimate. Thus, if future calculations of A2 and epsilon’/epsilon are to achieve 10% accuracy...
