Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

We provide an overview of the status of Monte-Carlo event generators for high-energy
particle physics. Guided by the experimental needs and requirements, we highlight areas of …

The accuracy of parton-shower simulations is often a limiting factor in the interpretation of
data from high-energy colliders. We present the first formulation of parton showers with …

A bstract In this work we perform the first ever calculation of jet event shapes at hadron
colliders at next-to-next-to leading order (NNLO) in QCD. The inclusion of higher order …

In cross sections with angular cuts, an intricate pattern of enhanced higher-order corrections
known as nonglobal logarithms arises. The leading logarithmic terms were computed …

A bstract We compute resummed and matched predictions for jet angularities in hadronic
dijet and Z+ jet events with and without grooming the candidate jets using the SoftDrop …

A bstract Non-global QCD observables are characterised by a sensitivity to the full angular
distribution of soft radiation emitted coherently in hard scattering processes. This complexity …

A bstract Jets and their substructure play a central role in many analyses at the Large
Hadron Collider (LHC). To improve the precision of measurements, as well as to enable …

A bstract The azimuthal angular decorrelation of a vector boson and jet is sensitive to QCD
radiation, and can be used to probe the quark-gluon plasma in heavy-ion collisions. By …

A bstract We present a systematic formalism based on a factorization theorem in soft-
collinear effective theory to describe non-global observables at hadron colliders, such as …
