In-medium QCD splittings beyond the soft, large- and harmonic-oscillator approximations all at once
Marco Leitão, José Guilherme Milhano, Alba Soto-Ontoso
Nearly thirty years ago, Baier, Dokshitzer, Mueller, Peigné, Schiff, and Zakharov (BDMPS-Z) introduced a formalism to calculate the fully differential probability for a high-energy…
Logarithmically-accurate showers with massive quarks
Melissa van Beekveld, Silvia Ferrario Ravasio, Alba Soto-Ontoso +2
We formulate PanScales final-state showers that account for quark masses and achieve next-to-leading logarithmic accuracy, while preserving the original accuracy of the showers for…
Bottom-up approach to describe groomed jet data in heavy-ion collisions
Liliana Apolinário, Diogo Costa, Alba Soto-Ontoso
The theoretical interpretation of jet observables in heavy-ion collisions is a complex task due to the intricate interplay of perturbative and non-perturbative effects. One way to…
Collinear spin correlations of final-state radiation in dense QCD matter
João M. Silva, Alba Soto-Ontoso
Spin correlations are required to reproduce the correct azimuthal dependence of matrix elements for successive branchings at disparate angles in QCD jets. In this paper, we study m…
A new suite of Lund-tree observables to resolve jets
Melissa van Beekveld, Luca Buonocore, Silvia Ferrario Ravasio +3
We introduce a class of collider observables, named Lund-Tree Shapes (LTS), defined from declustering trees originating from the Lund jet plane representation of the QCD radiation…
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…
Secondary Lund jet plane as a gluon enriched sample
Cristian Baldenegro, Alba Soto-Ontoso, Gregory Soyez
We propose a new strategy to obtain a high-purity sample of gluon-initiated jets at the LHC. Our approach, inspired by the Lund jet plane picture, is to perform a dijet selection w…
A generalized picture of colour decoherence in dense QCD media
Samuel Abreu, Xoán Mayo López, Guilherme Milhano +1
We revisit the calculation of the soft gluon emission probability off a colour-singlet system that evolves in a quark-gluon plasma. The antenna is created in th…
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…
Advancing the understanding of energy-energy correlators in heavy-ion collisions
João Barata, Paul Caucal, Alba Soto-Ontoso +1
We investigate the collinear limit of the energy-energy correlator (EEC) in a heavy-ion context. First, we revisit the leading-logarithmic (LL) resummation of this observable in va…
Introduction to the PanScales framework, version 0.1
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…
Isolating perturbative QCD splittings in heavy-ion collisions
Leticia Cunqueiro, Daniel Pablos, Alba Soto-Ontoso +3
We define a new strategy to scan jet substructure in heavy-ion collisions. The scope is multifold: (i) test the dominance of vacuum jet dynamics at early times, (ii) capture the tr…
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…
Exploring high-purity multi-parton scattering at hadron colliders
Jeppe R. Andersen, Pier Francesco Monni, Luca Rottoli +2
Multi-parton interactions are a fascinating phenomenon that occur in almost every high-energy hadron--hadron collision, yet are remarkably difficult to study quantitatively. In thi…
Lund multiplicity in QCD jets
Rok Medves, Alba Soto-Ontoso, Gregory Soyez
We compute the average Lund multiplicity of high-energy QCD jets. This extends an earlier calculation, done for event-wide multiplicity in collisions [arxiv:2205.02861], t…
Dead-cone searches in heavy-ion collisions using the jet tree
Leticia Cunqueiro, Davide Napoletano, Alba Soto-Ontoso
We explore the possibility of using the dead cone of heavy quarks as a region of the Lund plane where medium-induced gluon radiation can be isolated and characterised. The filling…
