| الوصف: | We consider leading-colour 2-, 3- and 4-jet rates in hadronic $Z$-boson decay to derive matching conditions at next-to-next-to-leading order in the sectorised VINCIA parton shower. In particular, we present a full subtraction-based calculation of the matching coefficient required to obtain the NLO 3-jet rate. This is achieved through a judicious choice of the counter-terms, which optimises the numerical evaluation of the subtracted double-real matrix element. We additionally give a consistent prescription for incorporating interference effects due to multiple Born states. Finally, we briefly comment on higher-order uncertainty estimates.
