Heavy quarkonium effective theory [PDF]

Zeitschrift für Physik C Particles and Fields, 1995
We formulate a QCD-based effective theory approach to heavy quarkonia-like systems as $\bar{c} c$ and $\bar{b} b$ resonances and $B_c$ states. We apply the method to inclusive decays, working out a few examples in detail.

Multiplicity Dependence of Quarkonium Production

Universe
Recent measurements on heavy-flavour production as a function of charged-particle multiplicity at the LHC are discussed. Focus is given to quarkonium results in small (pp or pPb) collision systems.

Quarkonium suppression in strongly coupled plasmas [PDF]

EPJ Web of Conferences
Suppression of open heavy quarks and quarkonia in heavy-ion collisions are among the most informative probes of quark-gluon plasma (QGP). Interpreting the full wealth of data obtained from the collision events requires a precise theoretical understanding

Next-to-leading-log renormalization-group running in heavy-quarkonium creation and annihilation [PDF]

, 2001
In the framework of potential NRQCD, we obtain the next-to-leading-log renormalization-group running of the matching coefficients for the heavy quarkonium production currents near threshold.

Direct quarkonium-plus-gluon production in DIS in the color glass condensate

Journal of High Energy Physics
We compute the differential cross-section for direct quarkonium production accompanied by a gluon in high-energy deep inelastic scattering (DIS) at small-x.

Nucleon-Quarkonium Elastic Scattering and the Gluon Contribution to Nucleon Spin

, 1999
It is shown that the amplitude for the scattering of a heavy quarkonium system from a nucleon near threshold is completely determined by the fraction of angular momentum, as well as linear momentum, carried by gluons in the nucleon.

Quarkonia Disintegration due to time dependence of the $q \bar{q}$ potential in Relativistic Heavy Ion Collisions

, 2014
Rapid thermalization in ultra-relativistic heavy-ion collisions leads to fast changing potential between a heavy quark and antiquark from zero temperature potential to the finite temperature one.
