Abstract
In this talk I investigate the interplay of NLO matching and next-to-leading-logarithmic (NLL) parton showers in the context of two-body decays. Three matching schemes have been implemented in the NLL-accurate PanScales showers: a multiplicative scheme, MC@NLO and POWHEG. By means of both analytic and numerical arguments, I show how these retain the showers NLL accuracy, and (under certain provisions in the case of POWHEG) can augment it so that it achieves NNDL accuracy for global event shapes. The talk also briefly explores some phenomenological considerations.
