Matching of logarithms of high-energy and of the parton shower have previously been reported for the (high energy) leading logarithmic component of the cross section, and only up to the first emission from PYTHIA.
We discuss a method for both extending this matching both to all orders, and to include the non-resummable component of the cross section through standard CKKW-L merging.
First results are presented from a flexible implementation using HEJ2 and PYTHIA, which also allows for matching of the recently calculated leading-logarithmic resummation of the first sub-leading processes.
