An effective field theory approach to quarkonium at small transverse momentum
Journal 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

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.

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.

Associated-quarkonium production [PDF]
Proceedings of XXII. International Workshop on Deep-Inelastic Scattering and Related Subjects — PoS(DIS2014), 2014 We discuss the growing interest to measure associated-quarkonium production in a number of channels at the LHC. Whereas back-to-back production of quarkonium + isolated photon provides a unique way to extract gluon TMDs, observables such as quarkonium + W/Z can be of great help to better understand the quarkonium production mechanism as well as to shed

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