Interference effects in the search for heavy Higgs bosons Interested people: Stefan Liebler, Jérémie Quevillon, Sabine Kraml, Alexandra Carvalho, Ramona Gröber, Tetiana Berger-Hryn'ova, Fabio Maltoni [add your names] Motivation: The search for additional heavy Higgs bosons is often carried out in the narrow width approximation, i.e. interferences of the Higgs bosons with the SM background as well as the light Higgs boson or other heavy Higgs bosons are neglected. The first analysis taking into…

Staged approach towards constraining the SMEFT at the LHC Interested people: Fabio Maltoni, Kristin Lohwasser... Motivation: Fiducial cross section measurements and STXS in Higgs physics are being developed and will provide non-maximally sensitive input to global SMEFT fits. Direct experimental top-down SMEFT interpretations of LHC SM measurements in Higgs and top physics have not yet taken off, due mostly to a difficulty of handling the richness and diversity of the many theoretical approac…

Large pT in POWHEG The issue is a significant hardening of the pT-spectrum after showering in POWHEG+Pythia8 for certain observables, even for non-zero values of the POWHEG damping factor (specific examples are gg->HH, see arXiv:1703.09252, or gg->H, see arXiv:1510.08850). Here are a few questions/topics that arose in the discussion:
