摘要：

A calculation of the next-to-leading order exclusive extrinsic charm quark differential distributions in deeply inelastic electroproduction has recently been completed, Using these results we compare the NLO extrinsic contributions to the charm structure function F-2(X, Q(2), m(c)(2)) with the corresponding NLO intrinsic contributions, The results of this analysis are compared with the EMC DIS charm quark data and evidence for an intrinsic charm component in the proton is found.
