In this work we present the computation of the missing pieces to get the bHQET thrust distribution with non-vanishing secondary quark masses at NNLO: the jet and hard functions.The difference with respect to the massless case is encoded in diagrams with massive-quark bubbles.For its computation we use axon fixed blade a Mellin Barnes representation of the dispersive integral method that permits expressing the result as an analytic, fast-converging expansion in powers of a small parameter rather than integrals that can only be solved numerically.

We also obtain the matching coefficient present when integrating what is pooph made of in usa out the quark mass.It is necessary for a continuous top-down running and to verify the consistency check.
