Relative phase between strong and electromagnetic amplitudes in psi(2S) to 0- 0- decays

Abstract

With the known branching ratios of psi(2S) to pi+pi- and psi(2S) to K+K-, the branching ratio of psi(2S) to K0short K0long is calculated as a function of the relative phase between the strong and the electromagnetic amplitudes of the psi(2S) decays. The study shows that the branching ratio of psi(2S) to K0short K0long is sensitive to the relative phase and a measurement of the K0short K0long branching ratio will shed light on the relative phase determination in psi(2S) to 0- 0- decays.
