An effective field theory approach to quarkonium at small transverse momentum

open access: yesJournal of High Energy Physics, 2020
In this work we apply effective field theory (EFT) to observables in quarkonium production and decay that are sensitive to soft gluon radiation, in particular measurements that are sensitive to small transverse momentum. Within the EFT framework we study

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

open access: yesJournal 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.

Quarkonium Spectral Functions [PDF]

open access: yesNuclear Physics A, 2009
In this talk I summarize the progress achieved in recent years on the understanding of quarkonium properties at finite temperature. Theoretical studies from potential models, lattice QCD, and effective field theories are discussed. I also highlight a bridge from spectral functions to experiment.

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

open access: yesPhysics 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.

Correct definition of color singlet P-wave non-perturbative matrix element of heavy quarkonium production

open access: yesJournal of High Energy Physics, 2017
Recently we have proved factorization of infrared divergences in NRQCD S-wave heavy quarkonium production at high energy colliders at all orders in coupling constant.

Space Dimension Renormdynamics

open access: yesParticles, 2020
We aim to construct a potential better suited for studying quarkonium spectroscopy. We put the Cornell potential into a more geometrical setting by smoothly interpolating between the observed small and large distance behaviour of the quarkonium potential.

Quarkonium in a thermal BIon [PDF]

open access: yesCanadian Journal of Physics, 2018
In the present article, the authors intend to propose a new theory that potentially allows the propagation of the formation and the evolution of quarkonium in a thermal BIon. When quarks are close to each other, quarkonium behaves like a scalar and, by their getting away, it transitions to a fermionic system.

A Guide to Light‐Cone PDFs from Lattice QCD: An Overview of Approaches, Techniques, and Results

open access: yesAdvances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019
Within the theory of Quantum Chromodynamics (QCD), the rich structure of hadrons can be quantitatively characterized, among others, using a basis of universal nonperturbative functions: parton distribution functions (PDFs), generalized parton distributions (GPDs), transverse momentum dependent parton distributions (TMDs), and distribution amplitudes ...
