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…
The Monte Carlo Ecosystem in High-Energy Physics: A Primer
Melissa van Beekveld, Enrico Bothmann, Andy Buckley +3
Monte Carlo event generators are the central interface between theoretical calculations and experimental measurements in collider physics. Over several decades, a comprehensive and…
Strangeness enhancement in pp collisions from string closepacking in Pythia 8.3
Javira Altmann, Lorenzo Bernardinis, Peter Skands +1
Measurements at LHC show an increased production of strange hadrons with charged multiplicity in pp collisions, which is not described by the Lund String Model (with the Monash tun…
Closepacking effects on strangeness and baryon production at the LHC
Javira Altmann, Lorenzo Bernardinis, Peter Skands +1
Data from the LHC show a rise in strange-hadron production with charged-particle multiplicity in pp collisions. The Monte-Carlo event generator PYTHIA, using its default Monash tun…
Physics case for low- QCD studies at FCC-ee
David d'Enterria, Pier Francesco Monni, Peter Skands +1
Measurements of hadronic final states in collisions at centre-of-mass (CM) energies below the Z peak can notably extend the FCC-ee physics reach in terms of precision…
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…
