Heavy Quarkonium Physics from Effective Field Theories [PDF]

, 2006
I review recent progress in heavy quarkonium physics from an effective field theory perspective. In this unifying framework, I discuss advances in perturbative calculations for low-lying quarkonium observables and in lattice calculations for high-lying ...

Excitation Function of Initial Temperature of Heavy Flavor Quarkonium Emission Source in High Energy Collisions

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
The transverse momentum spectra of J/ψ, ψ(2S), and Y(nS, n = 1, 2, 3) produced in proton‐proton (p + p), proton‐antiproton p+p¯, proton‐lead (p + Pb), gold‐gold (Au + Au), and lead‐lead (Pb + Pb) collisions over a wide energy range are analyzed by the (two‐component) Erlang distribution, the Hagedorn function (the inverse power‐law), and the Tsallis ...

Quarkonia as probes of initial and final states in small systems with ALICE [PDF]

EPJ Web of Conferences
The multiple parton−parton interactions (MPIs) are an important element to describe the observed collective flow and strangeness enhancement in high multiplicity pp and p−Pb collisions, the so-called small systems.

Masses and Thermodynamic Properties of a Quarkonium System

Canadian journal of physics (Print), 2021
Hulthen plus Hellmann potentials are adopted as the quark-antiquark interaction potential for studying the thermodynamic properties and the mass spectra of heavy mesons.

Fragmentation functions for a quark into a spin-singlet quarkonium: Different flavor case [PDF]

Physical Review D, 2021
In the paper, we calculate the fragmentation functions for a quark to fragment into a spin-singlet quarkonium, where the flavor of the initial quark is different from that of the constituent quark in the quarkonium.

Quarkonium Phenomenology from a Generalised Gauss Law

Universe, 2019
We present an improved analytic parametrisation of the complex in-medium heavy quark potential derived rigorously from the generalised Gauss law. To this end we combine in a self-consistent manner a non-perturbative vacuum potential with a weak-coupling ...

Quarkonium correlators and spectral functions at zero and finite temperature [PDF]

, 2006
We study quarkonium correlators and spectral functions at zero and finite temperature using the anisotropic Fermilab lattice formulation with anisotropy xi=2 and 4. To control cutoff effects we use several different lattice spacings.

Hidden-charm and bottom tetra- and pentaquarks with strangeness in the hadro-quarkonium and compact tetraquark models [PDF]

Journal of High Energy Physics, 2020
In two recent papers, we used the hadro-quarkonium model to study the properties of hidden-charm and bottom tetraquarks and pentaquarks. Here, we extend the previous results and calculate the masses of heavy-quarkonium-kaon/hyperon systems.

Breakdown of QCD factorization for P-wave quarkonium production at low transverse momentum

Physics Letters B, 2014
Quarkonium production at low transverse momentum in hadron collisions can be used to extract Transverse-Momentum-Dependent (TMD) gluon distribution functions, if TMD factorization holds there.
