Quarkonium production and polarization in pp collisions with the CMS detector

EPJ Web of Conferences, 2014
Studies of the production of heavy quarkonium states are very important to improve our understanding of QCD and hadron formation, given that the heavy quark masses allow the application of theoretical tools less sensitive to nonperturbative effects ...

Two-loop O(ϵ) term of 1/(mr2) heavy quarkonium potential

Physics Letters B
As a straightforward application of the recently calculated two-loop heavy quarkonium Hamiltonian, we evaluate the two-loop O(ϵ) term of the 1/(mr2) heavy quarkonium potential.

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

European 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.

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.

Production of the $P$-Wave Excited $B_c$-States through the $Z^0$ Boson Decays

, 2011
In Ref.[7],we have dealt with the production of the two color-singlet $S$-wave $(c\bar{b})$-quarkonium states $B_c(|(c\bar{b})_{\bf 1}[^1S_0]>)$ and $B^*_c(|(c\bar{b})_{\bf 1}[^3S_1]>)$ through the $Z^0$ boson decays.
