Anomalous scaling of linear power corrections
Casey Farren-Colloty, Jack Helliwell, Rtvik Patel +2
Non-perturbative corrections to hadronic observables represent a critical obstacle to increasing accuracy at colliders. Long taken to scale simply as , where is the centre…

Logarithmically-accurate and positive-definite NLO shower matching
Melissa van Beekveld, Silvia Ferrario Ravasio, Jack Helliwell +6
We present methods to achieve NLL+NLO accurate parton showering for processes with two coloured legs: neutral- and charged-current Drell-Yan, and Higgs production in collision…

Jettiness formulation of the MINNLO method
Markus Ebert, Luca Rottoli, Marius Wiesemann +2
We present a new formulation of the MINNLO method to match NNLO QCD calculations with parton showers by using jettiness as a resummation variable. The full derivation for colour-si…
