| Abstract: The azimuthal anisotropy of prompt $ \mathrm{D}_\mathrm{s}^{\pm} $ mesons in lead-lead collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV is measured using data obtained with the CMS detector. The dataset corresponds to an integrated luminosity of 0.58 nb$^{-1}$. The $ v_2 $ and $ v_3 $ Fourier coefficients are studied as a function of the $ \mathrm{D}_\mathrm{s}^{\pm} $ transverse momentum ($ p_\mathrm{T} $). The $ v_2 $ coefficient is determined in the range 4 $ < p_\mathrm{T} < $ 40 GeV/$c$ for three event centrality ranges, while the $ v_3 $ coefficient is measured in the range 4 $ < p_\mathrm{T} < $ 20 GeV/$c$ for one event centrality range. The results align with those observed for $ \mathrm{D}^{0} $ mesons, suggesting that the inclusion of a strange quark in the $ \mathrm{D}_\mathrm{s}^{\pm} $ meson has a minimal impact on the flow coefficients when these are compared to the non-strange $ \mathrm{D}^{0} $ meson within the measured $ p_\mathrm{T} $ range of the analysis. | ||
