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.

Quarkonium at Finite Temperature [PDF]
Nuclear Physics A, 2007 Lattice QCD studies on charmonium at finite temperature are presented After a discussion about problems for the Maximum Entropy Method applied to finite temperature lattice QCD, I show several results on charmonium spectral functions. The ``wave function'' of charmonium is also discussed to study the spatial correlation between quark and anti-quark in ...

, 2021 In this work, we obtain solutions of the Schrödinger equation with Kratzerscreened Coulomb potential (KSCP) model using the series expansion method. Explicitly, we compute the bound state energy eigenvalues for selected diatomic molecules of N2, CO, NO ...

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.

Space Dimension Renormdynamics
Particles, 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.

Entropic destruction of a moving heavy quarkonium
, 2015 Recently it has been shown that the peak of the quarkonium entropy at the deconfinement transition is related to the emergent entropic force which destructs the quarkonium.

Quarkonium Spectral Functions [PDF]
Nuclear 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.

Quarkonium in a thermal BIon [PDF]
Canadian 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.
