Webcalculation of the jet function as soft radiation has already been decoupled from the (leading order) collinear SCET Lagrangian by means of a field redefinition [4]. At one loop the quark jet function (i ¼ q) was computed in Refs. [17,18] and the gluon jet function (i ¼ g)in Ref. [19]. The two-loop results for J qðsÞ and J gðsÞ were WebIn this talk we consider the invariant mass distribution of top-jets and report about our computation of the two-loop heavy quark jet-function. This is a key part of a next-to-next-to-leading order analysis, and already allows for a resummation of all large logs which effect the shape of the top-invariant mass distribution at next-to-next-to-leading log order.
