Heavy Hybrids: decay to and mixing with Heavy Quarkonium

open access: yesEPJ Web of Conferences, 2017
We report on a recent QCD based research on hybrid mesons containing cc̄ or bb̄ quarks. We present results for the spectrum, the decay widths to heavy quarkonium, and the role of mixing with the latter.

Polarized Heavy Quarkonium Production in the Color Evaporation Model

open access: yes, 2017
We explore polarized heavy quarkonium production using the color evaporation model at leading order. We present the polarized to total yield ratio as a function of center of mass energy and rapidity in $p+p$ collisions.

Universal kinematic scaling as a probe of factorized long-distance effects in high-energy quarkonium production

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Dimensional analysis reveals general kinematic scaling rules for the momentum, mass, and energy dependence of Drell–Yan and quarkonium cross sections.

NRQCD: Fundamentals and Applications to Quarkonium Decay and Production

open access: yes, 2005
I discuss NRQCD and, in particular, the NRQCD factorization formalism for quarkonium production and decay. I also summarize the current status of the comparison between the predictions of NRQCD factorization and experimental measurements.Comment: 8 pages,

NRQCD Factorization and Quarkonium Production at Hadron-Hadron and ep Colliders

open access: yes, 2010
I review the NRQCD factorization approach for quarkonium production and compare its predictions with measurements in hadron-hadron and ep collisions.Comment: 6 pages, contribution to the proceedings of Charm 2010, IHEP, Beijing, October 21-24 ...

Quarkonium Level Spacings

open access: yesPhysics Letters B, 1977
Motivated by the apparent equal spacing M (ϒ′) - M (ϒ) = M ψi) - M (ψ), we show that the potential for which quarkonium level spacings are independent of quark mass, in the nonrelativistic limit, is V ( r ) = C In ( r / r 0 ). We enumerate consequences of the logarithmic potential and present an alternative interpretation of the data.

Quarkonium Suppression from Coherent Energy Loss in Fixed-Target Experiments Using LHC Beams

open access: yesAdvances in High Energy Physics, 2015
Quarkonium production in proton-nucleus collisions is a powerful tool to disentangle cold nuclear matter effects. A model based on coherent energy loss is able to explain the available quarkonium suppression data in a broad range of rapidities, from ...
