Abstract Quark–Gluon Plasma (QGP), a QCD state of matter created in ultra-relativistic
heavy-ion collisions, has remarkable properties including, for example, a low shear viscosity …

The many ways in which machine and deep learning are transforming the analysis and
simulation of data in particle physics are reviewed. The main methods based on boosted …

A bstract Jet production in lead-lead (PbPb) and proton-proton (pp) collisions at a nucleon-
nucleon center-of-mass energy of 5.02 TeV is studied with the CMS detector at the LHC …

A bstract Measurements of jet substructure describing the composition of quark-and gluon-
initiated jets are presented. Proton-proton (pp) collision data at\(\sqrt {s}\)= 13 TeV collected …

This report, as part of the 2021 Snowmass Process, summarizes the current status of collider
physics at the Energy Frontier, the broad and exciting future prospects identified for the …

This handbook provides a comprehensive review of transverse-momentum-dependent
parton distribution functions and fragmentation functions, commonly referred to as …

The future opportunities for high-density QCD studies with ion and proton beams at the LHC
are presented. Four major scientific goals are identified: the characterisation of the …

In this addendum to Ref., we update our results to include the recent measurement of R (D)
and R (D*) by the Belle Collaboration: R (D) Belle= 0.307±0.037±0.016 and R (D*) Belle …

We present next-to-next-to-next-to-leading order (N 3 LO) QCD predictions for the Higgs
boson pair production via gluon fusion at hadron colliders in the infinite top-quark mass limit …

Starting from the observation that artificial neural networks are uniquely suited to solving
optimization problems, and most physics problems can be cast as an optimization task, we …
