Characterising hadronisation across the phase space
Andrea Banfi, Basem Kamal El-Menoufi
Leading hadronisation corrections to two-jet global event shapes amount to a shift in the corresponding perturbative distributions. It has been recently established that this shift…
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…
A collinear shower algorithm for NSL non-singlet fragmentation
Melissa van Beekveld, Mrinal Dasgupta, Basem Kamal El-Menoufi +3
We formulate a collinear partonic shower algorithm that achieves next-to-single-logarithmic (NSL, ) accuracy for collinear-sensitive non-singlet fragmentation observ…

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…
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…

Melissa van Beekveld, Mrinal Dasgupta, Basem Kamal El-Menoufi +11
In this article, we document version 0.1 of the PanScales code for parton shower simulations. With the help of a few examples, we discuss basic usage of the code, including tests o…
Rational Q-systems at Root of Unity I. Closed Chains
Jue Hou, Yunfeng Jiang, Yuan Miao
The solution of Bethe ansatz equations for XXZ spin chain with the parameter being a root of unity is infamously subtle. In this work, we develop the rational -system for th…
Collinear fragmentation at NNLL: generating functionals, groomed correlators and angularities
Melissa van Beekveld, Mrinal Dasgupta, Basem Kamal El-Menoufi +2
Jet calculus offers a unique mathematical technique to bridge the area of QCD resummation with Monte Carlo parton showers. With the ultimate goal of constructing next-to-next-to-le…
Interplay between perturbative and non-perturbative effects with the ARES method

We present a new semi-numerical method to compute leading hadronisation corrections to two-jet event shapes in annihilation. The formalism we present utilises the dispersi…
QCD resummation for groomed jet observables at NNLL+NLO

We use a direct QCD approach to carry out the next-to-next-to-leading logarithmic (NNLL) resummation for observables groomed with the modified mass-drop tagger (Soft Drop ). W…
Dissecting the collinear structure of quark splitting at NNLL
Mrinal Dasgupta, Basem Kamal El-Menoufi
We explore the collinear limit of final-state quark splittings at order . While at general NLL level, this limit is described simply by a product of leading-order D…

Daniele Anderle, Mrinal Dasgupta, Basem Kamal El-Menoufi +2
We study the link between parton dynamics in the collinear limit and the logarithmically enhanced terms of the groomed jet mass distribution, for jets groomed with the modified mas…

We extend the ARES method for next-to-next-to-leading-logarithmic (NNLL) QCD resummations to three-jet event shapes in collisions in the near-to-planar limit. In particul…

The effective field theory of quantum gravity generically predicts non-locality to be present in the effective action, which results from the low-energy propagation of gravitons an…
