Soft gluon resummation for heavy quark electroproduction - art. no. 034027.

We present the threshold resummation for the cross section for electroprodu ction of heavy quarks. We work to next-to-leading logarithmic accuracy and in single-particle inclusive kinematics. We provide next-to-leading and nex t-to-next-to-leading order expansions of our resummed formula, and examine numerically the quality of these finite order approximations. For the case of charm we study their impact on the structure function F-2 and its differ ential distribution with respect to the charm transverse momentum. [S0556-2 821(99)03603-6].
