    The unquenched quark model by Santopinto E., Ferretti J.

    Published 2015-01-01
    “…In this contribution, we briefly discuss the results for charmonium and bottomonium spectra with self-energy corrections in the unquenched quark model, due to the coupling to the meson-meson continuum The UQM formalism can be extended to include also the effects of hybrid mesons, i.e. hybrid loops. …”

    Quark model description of baryon properties by Metsch Bernard Ch., Petry Herbert-R.

    Published 2017-01-01
    “…The basis of the calculations was a relativistically covariant quark model for mesons and baryons, which allows for the calculation of (momentum dependent) hadronic form factors and coupling vertices in the relevant photon and hadron induced reactions and simultaneously describes the hadronic mass spectrum up to 3 GeV.…”

    Prediction of charmed-bottom pentaquarks in quark model by Ye Yan, Yuheng Wu, Hongxia Huang, Jialun Ping, Xinmei Zhu

    Published 2023-07-01
    “…Abstract Inspired by the fully heavy tetraquark states reported by the LHCb, ATLAS and CMS Collaborations, we perform a systematical investigation of the low-lying fully heavy pentaquark systems composed of charm and bottom quarks (anti-quark) in the chiral quark model. With the help of the channel-coupling, we obtain several fully heavy pentaquark candidates, which are $$cccc\bar{b}$$ c c c c b ¯ and $$bbbb\bar{c}$$ b b b b c ¯ systems with $$J^P = 1/2^-$$ J P = 1 / 2 - and $$3/2^-$$ 3 / 2 - , $$cccb\bar{c}$$ c c c b c ¯ , $$bbbc\bar{b}$$ b b b c b ¯ , $$cccb\bar{b}$$ c c c b b ¯ and $$bbbc\bar{c}$$ b b b c c ¯ systems with $$J^P = 5/2^-$$ J P = 5 / 2 - . …”
