2. Study of charmonium production with the LHCb

Valeriia Zhovkovska (Université Paris-Saclay (FR))

22/03/2021, 10:20

Inclusive reactions (incl. jets & isolation) & tools for PDFs

This contribution is devoted to understanding charmonium production mechanism using data from the LHCb experiment. It also suggests an exploration of new observables and proposes a series of new approaches on charmonia studies in LHCb. It will describe a possible extension of a series of breakthrough studies, performed at IJCLab (former LAL) and UCAS within the LHCb collaboration and...

8. Multiplicity depedence of quarkonium production

Inclusive reactions (incl. jets & isolation) & tools for PDFs

At the LHC collision energies, multiple parton interactions (MPI) are a key ingredient for particle production models including hard scale processes like heavy-quark production (charm and beauty). Multiplicity dependent quarkonium measurements can shed light on the role of MPI at such hard momentum scales, as well as on the interplay between hard and soft particle production mechanisms. Such...

3. Physics with charmonia at the SPD experiment

Igor Denisenko (Joint Institute for Nuclear Research (RU))

Reactions with polarisation & tools for TMD functions, spin asymmetries,...

The SPD experiment is planned to operate at the second interaction point of the NICA facility, which is under construction at the JINR. The primary goal of the experiment is a comprehensive study of the polarized and unpolarized gluon structure of proton and deuteron in polarized $pp$, $dd$, and $pd$ collisions at $\sqrt{s}$ up to 27 GeV and luminosity up to $10^{32}$cm$^{-2}$s$^{-1}$. Several...

22. X(3872) production and suppression

Kevin Ingles (Ohio State University)

22/03/2021, 16:00

I review the literature on charmonium suppression in hadronic collisions, and why understanding the source of the suppressions observed are important.
I highlight models that have failed and succeeded at explaining this suppression, and what physics these models adopt to account for the suppressions.
Finally, I discuss a new model that is physically well motivated, and also applies to...

13. Production and polarization of direct $J/\psi$ to ${\mathcal O}(\alpha_s^3)$ in the improved color evaporation model in collinear factorization

Vincent Cheung (LLNL)

Inclusive reactions (incl. jets & isolation) & tools for PDFs

One of the best ways to understand hadronization in QCD is to study the production of quarkonium. The color evaporation model (CEM) and Nonrelativistic QCD (NRQCD) can describe production yields rather well but spin-related measurements like the polarization are stronger tests. In this talk, we will present the first calculation of quarkonium polarization in the improved color evaporation...

12. Exploring $J/\psi$ production mechanism at the future Electron-Ion Collider

XIANGPENG WANG (Argonne National Laboratory)

Inclusive reactions (incl. jets & isolation) & tools for PDFs

We propose to use transverse momentum $p_T$ distribution of $J/\psi$ production at the future Electron Ion Collider (EIC) to explore the production mechanism of heavy quarkonia in high energy collisions. We apply QCD and QED collinear factorization to the production of a $c\bar{c}$ pair at high $p_T$, and non-relativistic QCD factorization to the hadronization of the pair to a $J/\psi$. We...

15. Large-P_T inclusive photoproduction of J/ψ in electron-proton collisions at HERA and the EIC

Yelyzaveta Yedelkina (Paris-Saclay University)

22/03/2021, 17:40

We study the inclusive J/ψ production at large transverse momenta at lepton-hadron colliders in the limit when the exchange photon is quasi real, also referred to as photoproduction. Our computation includes the leading- PT leading- v next-to-leading αs corrections. In particular, we consider the contribution from J/ψ plus another charm quark, by employing for the first time in quarkonium...
