A golden age for heavy-quarkonium physics dawned a decade ago, initiated by the
confluence of exciting advances in quantum chromodynamics (QCD) and an explosion of …

We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

We discuss the various mechanisms potentially at work in hadroproduction of heavy
quarkonia in the light of computations of higher-order QCD corrections both in the colour …

The polarizations of the Y (1S), Y (2S), and Y (3S) mesons are measured in proton-proton
collisions at sqrt (s)= 7 TeV, using a data sample of Y (nS) to oppositely charged muon pair …

We update the theoretical predictions for direct Υ (n S) hadroproduction in the framework of
nonrelativistic QCD. We show that the next-to-leading order corrections in α S to the color …

+ 1. 64− 2. 20 µb for prompt J/ψ production and 1. 14±0. 01±0. 16 µb for J/ψ from b-hadron
decays, where the first uncertainty is statistical and the second systematic. The prompt J/ψ …

Using 1.8 fb-1 of pp collisions at a center-of-mass energy of 7 TeV recorded by the ATLAS
detector at the Large Hadron Collider, we present measurements of the production cross …

The production of ϒ (1 S), ϒ (2 S) and ϒ (3 S) mesons in proton-proton collisions at the
centre-of-mass energy of s=7~TeV is studied with the LHCb detector. The analysis is based …

We present a technique for translating a black-box machine-learned classifier operating on
a high-dimensional input space into a small set of human-interpretable observables that can …

The polarizations of the Υ (1 S), Υ (2 S), and Υ (3 S) mesons are measured in proton-proton
collisions at s= 7 TeV, using a data sample of Υ (n S)→ μ+ μ-decays collected by the CMS …
