NEUTRON STRUCTURE-FUNCTION FROM THE CONVOLUTION FORMALISM AND THE QUARK-PARTON MODEL

A hybrid model is proposed to extract the electromagnetic neutron structure function by combining the convolution formalism in the small-x region and the quark-parton model in the medium- to large-x region. (mu-p)- and (mu-d)-data in the small-x region, and (mu-p)-, (nu-p)- and (nu-pBAR)-data in the large-x region are combined. Possible inconsistencies in mixing the nu, nu-dataBAR with mu-data are carefully sorted out. The new method can circumvent both the experimental anomaly between the (mu-p)- and (mu-d)-data and the theoretical ambiguity of using the nonrelativistic spectroscopic function in the large-x region.
