Measurements of the elliptic (v(2)) and triangular (v(3)) azimuthal anisotropy coefficients are presented for D-0 mesons produced in b hadron decays (nonprompt D-0 mesons) in lead-lead collisions at root s(NN) = 5.02 TeV. The results are compared with previously published charm meson anisotropies measured using prompt D-0 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 D-0 mesons can assist in understanding the mass dependence of these interactions. The nonprompt results show lower magnitudes of v(2) and v(3) and weaker dependences on the meson transverse momentum and collision centrality than those found for prompt D-0 mesons. The results are in agreement with theoretical predictions that include a mass dependence in the interactions of quarks with the medium.
