Nuclear transparencies for nucleons, knocked-out under various semi-inclusive conditions.

Using hadron dynamics we calculate nuclear transparencies for protons, knocked-out in high-{ital Q}{sup 2}, semi-inclusive reactions. Predicted transparencies 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 compare 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 attributed to exotic components in the description of the outgoing proton.
