Abstract: | <p> Experimental and theoretical investigations on charge dependence and charge asymmetry in N-N and λ-N interactions are reviewed. The γ-π-exchange N-N and λ-N potentials are derived and calculated in the static limit. The γ-π-exchange charge dependent component of the N-N potential is found to be larger than the charge dependent part of OPEP due to pion mass difference up to 3 fm and is of opposite sign, making the explanation of the splitting between p-n and p-p scattering lengths more difficult than was previously thought. Except at very short distances, this potential is of the order of only a few percent of the OPEP. In the light of this result, it is concluded that the very large charge-dependent correction at large distances required by Noyes' phenomenological analysis on the splitting of rpn and rpp is inexplicable as an electromagnetic correction. The γ-π exchange charge asymmetric components of both N-N and λ-N interactions are found to be much weaker than the charge dependent one for the N-N case.</p> |
