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…
Threshold resummation for the production of four top quarks at the LHC
Melissa van Beekveld, Anna Kulesza, Laura Moreno Valero
We compute the total cross section for production at next-to-leading logarithmic (NLL) accuracy. This is the first time resummation is performed for a…
Invariant-mass threshold resummation for the production of four top quarks at the LHC
Melissa van Beekveld, Anna Kulesza, Michele Lupattelli +1
Using invariant-mass threshold resummation, we compute the invariant-mass distribution and the total cross section for production at the LHC with centre-of-mass…
A Phenomenological Analysis of LHC Neutrino Scattering at NLO Accuracy Matched to Parton Showers
Melissa van Beekveld, Silvia Ferrario Ravasio, Eva Groenendijk +3
We perform a detailed phenomenological study of high-energy neutrino deep inelastic scattering (DIS) focused on LHC far-forward experiments such as FASER and SND@LHC. To this a…
Two-loop anomalous dimensions for small- jet versus hadronic fragmentation functions
Melissa van Beekveld, Mrinal Dasgupta, Basem Kamal El-Menoufi +3
We study the collinear fragmentation of highly energetic jets defined with a small jet radius. In particular, we investigate how the corresponding fragmentation functions differ fr…
