Timelike showers with jet recoils
Jack Helliwell, Ludovic Scyboz, Peter Skands
We propose a new way to impose four-momentum conservation on timelike parton-shower branchings, allowing for recoil to be imparted not only to individual partons but also to groups…
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…
