NUCLEAR TRANSPARENCIES FOR NUCLEONS, KNOCKED-OUT UNDER VARIOUS SEMIINCLUSIVE CONDITIONS

Using hadron dynamics we calculate nuclear transparencies for protons, knocked-out in high-Q(2), semi-inclusive reactions. Predicted transpa rencies are roughly half a standard deviation above the NE18 data. The latter contain the effects of binned proton missing momenta and mass, and of finite detector acceptances. In order to test sensitivity we c ompare computed transparencies without restrictions and the same with maximal cuts for missing momenta and the electron energy loss. We find hardly any variation, enabling a meaningful comparison with data and predictions based on hadron dynamics. Should discrepancies persist in high-statistics data, the above may with greater confidence be attribu ted to exotic components in the description of the outgoing proton.
