This document provides a comprehensive summary of the state-of-the-art, challenges, and
prospects in the experimental and theoretical study of the strong coupling $\alpha_s $. The …

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 …

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 An intuitive definition of the partonic flavor of a jet in quantum chromodynamics is
often only well-defined in the deep ultraviolet, where the strong force becomes a free theory …

A bstract Energy correlators measured inside high-energy jets at hadron colliders have
recently been demonstrated to provide a new window into both perturbative and non …

We study quark and gluon jets separately using public collider data from the CMS
experiment. Our analysis is based on 2.3 fb− 1 of proton-proton collisions at s= 7 TeV …

A bstract 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 …

A bstract We compute the average Lund multiplicity of high-energy QCD jets. This extends
an earlier calculation, done for event-wide multiplicity in e+ e− collisions [1], to the large …
