arXiv:nucl-th/9506023v1 26 Jun 1995 Rho-Omega Mixing Off Shell and Charge Symmetry Breaking In the N-N Potential Thomas D. Cohen a,b ∗ , and Gerald A. Miller a Department of Physics a FM-15 and Institute For Nuclear Theory b NK-12, University of Washington, Seattle, Washington 98195, USA Abstract The role of the off-shell dependence of ρ − ω mixing in the charge symmetry breaking nucleon-nucleon potential is discussed. It is shown that models de- scribing the off-shell dependence of ρ−ω mixing are not sufficient to determine the charge symmetry breaking nucleon-nucleon potential. ∗ Permanent address: Department of Physics and Center for Theoretical Physics, University of Maryland, College Park, MD 20742, USA 1
