| dc.description.abstract | We present an antenna shower formalism that includes helicity dependence for massless partons. The formalism applies to both traditional (global) showers and sector-based variants. We combine the shower with vincia’s multiplicative approach to matrix-element matching, generalized to operate on each helicity configuration separately. The result is a substantial gain in computational speed for high parton multiplicities. We present an implementation of both sector and global showers, with min/max variations, and helicity-dependent tree-level matching applied through n≤4 for V/H→qq̅ +n partons and through n≤5 for H→n gluons. | en_US |
