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…
Matching Z Hadrons at NNLO with Sector Showers
Basem Kamal El-Menoufi, Christian T. Preuss, Ludovic Scyboz +1
We present a detailed technical derivation of matching conditions at next-to-next-to-leading order in the sectorised VINCIA parton shower, by considering leading-colour 2-, 3- and…
Flavoured jet algorithms: a comparative study
Arnd Behring, Simone Caletti, Francesco Giuli +17
The accurate identification of heavy-flavour jets, those which originate from bottom or charm quarks, is crucial for precision studies of the Standard Model and searches for new ph…
A new standard for the logarithmic accuracy of parton showers
Melissa van Beekveld, Mrinal Dasgupta, Basem Kamal El-Menoufi +9
We report on a major milestone in the construction of logarithmically accurate final-state parton showers, achieving next-to-next-to-leading-logarithmic (NNLL) accuracy for the wid…
