Born-Oppenheimer approximation in EFT and quarkonium hybrids

EPJ Web of Conferences, 2017
We report on the results of [1] for the calculations of quarkonium hybrids. We have developed and Effective Field Theory (EFT) for quarkonium hybrids that systematically incorporates an expansion with respect to the adiabatic limit.

Two-loop integrals for CP-even heavy quarkonium production and decays

Journal of High Energy Physics, 2017
By employing the method of differential equations, we compute the various types of two-loop master integrals involved in CP-even heavy quarkonium exclusive production and decays.

ϒ(1S) transverse momentum spectra through dissociation and regeneration in heavy-ion collisions

Physics Letters B, 2020
We calculate the transition between a quarkonium state and an unbound heavy quark-antiquark pair through gluo-dissociation and inelastic parton scattering using a partonic picture that interpolates between the formal limits based on potential ...

Quarkonium polarization as a test of non-relativistic effective theory [PDF]

, 1997
I compare current approaches to quarkonium production with regard to what they tell us about quarkonium polarization. Predictions for $J/\psi$ polarization in hadron-hadron and photon-hadron collisions are summarized.Comment: 6 pages, LaTeX, 3 figures ...

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.

Long-Range Forces of QCD [PDF]

, 1999
We consider the scattering of two color dipoles (e.g., heavy quarkonium states) at low energy - a QCD analog of Van der Waals interaction. Even though the couplings of the dipoles to the gluon field can be described in perturbation theory, which leads to

Quarkonium Production at STAR [PDF]

Proceedings of XXIst International Europhysics Conference on High Energy Physics — PoS(EPS-HEP2011), 2012
We report the results on heavy quarkonium production in p+p and Au+Au collisions at midrapidity via the dielectron decay channel at sqrt(s_NN) = 200 GeV from the STAR experiment at RHIC. Results on the J/psi p_T spectra in p+p collisions are presented for 2 < p_T < 10 GeV/c. The B-meson feed-down contribution to the inclusive J/psi yield has been

Heavy Quarkonium States With Baryonic Chemical Potential

Advances in High Energy Physics
In this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential.

Inclusive double-quarkonium production at the Large Hadron Collider

, 2011
Based on the nonrelativistic QCD (NRQCD) factorization formalism, we investigate inclusive productions of two spin-triplet S-wave quarkonia pp->2J/psi+X, 2Upsilon+X, and J/psi+Upsilon+X at the CERN Large Hadron Collider.
