Strong and electromagnetic amplitudes of the J/ψ decays into baryons and their relative phase

The Feynman amplitude for the decay of the J/ψ meson into baryon-antibaryon can be written as a sum of three sub-amplitudes: a purely strong, a purely electromagnetic and a mixed strong-electromagnetic. Assuming that the strong and mixed strong-electromagnetic sub-amplitudes have the same phase, the...
