Samenvatting

Measurements of the second Fourier harmonic coefficient (v ₂) of the azimuthal distributions of prompt and nonprompt D ⁰ mesons produced in pp and pPb collisions are presented. Nonprompt D ⁰ mesons come from beauty hadron decays. The data samples are collected by the CMS experiment at nucleon-nucleon center-of-mass energies of 13 and 8.16 TeV, respectively. In high multiplicity pp collisions, v ₂ signals for prompt charm hadrons are reported for the first time, and are found to be comparable to those for light-flavor hadron species over a transverse momentum (p _T) range of 2–6 GeV. Compared at similar event multiplicities, the prompt D ⁰ meson v ₂ values in pp and pPb collisions are similar in magnitude. The v ₂ values for open beauty hadrons are extracted for the first time via nonprompt D ⁰ mesons in pPb collisions. For p _T in the range of 2–5 GeV, the results suggest that v ₂ for nonprompt D ⁰ mesons is smaller than that for prompt D ⁰ mesons. These new measurements indicate a positive charm hadron v ₂ in pp collisions and suggest a mass dependence in v ₂ between charm and beauty hadrons in the pPb system. These results provide insights into the origin of heavy-flavor quark collectivity in small systems.
