Description

We give a status report on new developments in the WHIZARD event generator,
including NLO electroweak automation for e+e-, loop-induced processes, POWHEG
matching, new features in the UFO interface and the current development for
matching between exclusive photon radiation and fixed-order LO/NLO EW
corrections. We report on several bug fixes relevant for certain aspects of the
ILC250 MC mass production, especially on the normalization of matching EPA
samples with full-matrix element samples. Finally, we mention some ongoing
work on efficiency improvements regarding parallelization of matrix elements
and phase space sampling, as well as plans to revive the top threshold
simulation.
