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-energ…
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…
