    Viscosity vs. vorticity in the quark-gluon plasma by Brett McInnes

    Published 2020-04-01
    “…We show that, in a holographic or gauge-gravity approach to the study of the Quark-Gluon Plasma, the specific entropy density of the plasma produced in a peripheral heavy-ion collision can be strongly suppressed relative to its value for central collisions at the same impact energy; this is connected with the strong vorticity fields which are now known to characterize the peripheral case. …”

    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 - . …”

    A method for probing the formation of quark matter by Gao-Chan Yong

    Published 2023-08-01
    “…Given parton scatterings as a signal of the formation of quark matter, the transverse momentum distribution of the ratio of single and double strangeness (Λ+Σ0)/Ξ− produced in heavy-ion collisions may serve as a potential probe of the emergence of quark matter, or equivalently, the occurrence of hadron-quark phase transition in relativistic heavy-ion collisions.…”
