We present a parameter-free scheme to combine fixed-order multi-jet results with parton-shower evolution. The scheme produces jet cross sections with leading-order accuracy in the complete phase space of multiple emissions, resumming large logarithms when appropriate, while not arbitrarily enforcing ordering on momentum configurations beyond the reach of the parton-shower evolution equation. This requires the development of a matrix-element correction scheme for complex phase-spaces including…

This work presents an extension of the CKKW-L multi-jet merging technique to so-called sector showers as implemented in the Vincia antenna shower, and reduces the factorial scaling of the number of parton shower histories to a constant of a single history per colour-ordered final state.

In conventional parton showers (including ones based on dipoles/antennae), a given (Born + m )-parton configuration can typically be reached via O ( m !) different “shower histories”. In the context
