  1. 190. Quarkonium production in pp and pPb collisions at the LHC
    Jaebeom Park (Korea University (KR))
    29/11/2022, 16:00
    WG4: Heavy-quark and Quarkonium Physics

    Quarkonia has been long regarded as golden probes to study the fundamental (de)confinement of Quantum Chromodynamics (QCD). Understanding their production provided crucial information for the physics on non-perturbative QCD factorization. However, the mechanism behind the production of various quarkonium states are still under investigation even after ~50 years from the discovery of the J/Psi...

  2. 72. Associated production of J/psi plus W or Z at NLO and implications on NRQCD factorization.

    WG4: Heavy-quark and Quarkonium Physics

    We present our next-to-leading order (NLO) calculation of associated hadroproduction of J/psi plus W or Z bosons within the factorization framework of nonrelativistic QCD (NRQCD). We compare to ATLAS data using various sets of nonperturbative long distance matrix elements (LDMEs) as input, thereby opening up a completely new angle in the ongoing quest to understand whether the LDMEs are...

  3. 13. S-wave quarkonium production and polarization in potential NRQCD
    Xiangpeng Wang (Technische Universität München)

    WG4: Heavy-quark and Quarkonium Physics

    Based on the potential nonrelativistic QCD formalism, we compute the nonrelativistic QCD long-distance matrix elements (LDMEs) for inclusive production of S-wave heavy quarkonia. This greatly reduces the number of nonperturbative unknowns and brings in a substantial enhancement in the predictive power of the nonrelativistic QCD factorization formalism. We obtain improved determinations of the...

  4. 147. Exotic Hadrons at LHC
    Mindaugas Sarpis (University of Bonn (DE))

    WG4: Heavy-quark and Quarkonium Physics

    An overview of the most recent experimental results by LHCb, CMS and ATLAS collaborations of the LHC on analyses involving exotic hadrons
