  1. 61. The system-size dependence of the bottom-baryon-to-meson production in high-energy proton-proton collisions

    3. Heavy quarks and quarkonia
    Oral presentation

    The latest measurement of bottom baryon-to-meson production ratio [1], $\Lambda_b/B$, in proton-proton collisions at the LHC, shows a continuous evolution from the saturation value toward the small value identified in electron-positron collisions as the system size reduces. We address this in a canonical ensemble statistical hadronization model, and demonstrate that the decreasing trend of...

  2. 48. The role of strangeness in heavy quark hadronisation from small to large collision systems with ALICE

    3. Heavy quarks and quarkonia
    Oral presentation

    Production measurements of strange hadrons originating from the hadronisation of charm quarks (prompt) and from beauty-hadron decays (non-prompt) offer a unique tool to study the heavy-quark hadronisation across different collision systems. The comparisons between the measurements of charm hadrons with and without a strange valence quark in proton-proton (pp) and proton-lead (p-Pb) collisions...

    3. Heavy quarks and quarkonia
    Oral presentation

    Charm quarks produced in the initial stages of relativistic heavy-ion collisions serve as crucial probes of the produced medium, including the pre-equilibrium and hydrodynamic stages of the evolution. We simulate relativistic heavy-ion collisions using a hybrid method that integrates a fluctuating IP-Glasma initial state with subsequent viscous hydrodynamics. Utilizing the MARTINI event...

  4. 257. Medium-induced coherent gluon radiation and heavy flavor suppression in pA collisions

    3. Heavy quarks and quarkonia
    Oral presentation

    High-energy proton-nucleus (pA) collisions have provided intriguing playgrounds for disentangling various cold nuclear matter effects on hadron production. Multiple rescatterings in the cold nuclear target induce many soft gluons that have a long formation time, resulting in the modification of hadron production rates due to fully coherent energy loss (FCEL). Medium-induced FCEL has proven to...
