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 …

After an introduction motivating the study of quarkonium production, we review the recent
developments in the phenomenology of quarkonium production in inclusive scatterings of …

This article reviews recent theoretical developments in heavy-quarkonium physics from the
point of view of effective-field theories of QCD. We discuss nonrelativistic QCD and …

The production of two prompt J/ψ J/ψ mesons, each with transverse momenta p_ T> 8.5 p T>
8.5 GeV and rapidity| y|< 2.1| y|< 2.1, is studied using a sample of proton-proton collisions at …

The theoretical description of heavy quarkonium production at high-energy pp and ep
colliders is reviewed. Predictions based on non-relativistic QCD factorisation are confronted …

Basic physical characteristics of doubly heavy baryons are examined, including
spectroscopy (which is treated in the potential approach and within the QCD sum rules …

We calculate the spectrum of the charm-beauty mesons using the relativized quark model.
Using the wave functions from this model we compute the radiative widths of excited cb¯ …

We investigate the inclusive hadroproduction of a heavy quarkonium (\(J/\psi\) or\(\Upsilon\)),
in association with a light-flavored jet, as a testing ground for the semi-hard regime of QCD …

The color evaporation model simply states that charmonium production is described by the
same dynamics as DD production, ie, by the formation of a colored cc pair. Its color happens …

Applying asymptotic expansions at threshold, we compute the two-loop quantum
chromodynamics (QCD) correction to the short-distance coefficient that governs the leptonic …
