Relativistic distorted-wave impulse approximation analysis of 12C(e,e'p) for Q2<2 (GeV/c)2

We analyze data for 12C(e,e'p) with Q2<2 (GeV/c)2 using the relativistic distorted-wave impulse approximation (RDWIA) based upon Dirac-Hartree wave functions. The 1p normalization extracted from data for Q2>0.6 (GeV/c)2 is approximately 0.87, independent of Q2, which is consistent with the predicted depletion of the 1p3/2 orbital by short-range correlations. The total 1p and 1s strength for Em<80 MeV approaches 100% of IPSM (independent particle shell model), consistent with a continuum contribution for 300.6 (GeV/c)2, the effect is smaller, and we argue that it should be attributed to the effective single-nucleon current operator instead of to spectroscopic factors, which are probe-independent properties of nuclear structure. However, remediation of the failure of RDWIA calculations to reproduce low Q2 data for parallel kinematics will require a more sophisticated modification of the current method than a simple multiplicative factor
