Measurements of azimuthal anisotropy of nonprompt D0 mesons in PbPb collisions at s NN = 5.02 TeV

Measurements of azimuthal anisotropy of nonprompt D0 mesons in PbPb collisions at s NN = 5.02 TeV

Measurements of the elliptic ( v2 ) and triangular ( v3 ) azimuthal anisotropy coefficients are presented for Image 1 mesons produced in Image 2 hadron decays (nonprompt Image 1 mesons) in lead-lead collisions at s NN = 5.02 TeV . The results are compared with previously published charm meson anisot...

Zusammenfassung:Measurements of the elliptic ( v2 ) and triangular ( v3 ) azimuthal anisotropy coefficients are presented for Image 1 mesons produced in Image 2 hadron decays (nonprompt Image 1 mesons) in lead-lead collisions at s NN = 5.02 TeV . The results are compared with previously published charm meson anisotropies measured using prompt Image 1 mesons. The data were collected with the CMS detector in 2018 with an integrated luminosity of 0.58 nb − 1 . Azimuthal anisotropy is sensitive to the interactions of quarks with the hot and dense medium created in heavy ion collisions. Comparing results for prompt and nonprompt Image 1 mesons can assist in understanding the mass dependence of these interactions. The nonprompt results show lower magnitudes of v2 and v3 and weaker dependences on the meson transverse momentum and collision centrality than those found for prompt Image 1 mesons. The results are in agreement with theoretical predictions that include a mass dependence in the interactions of quarks with the medium.
