Measurement of Prompt D0 Meson Azimuthal Anisotropy in Pb-Pb Collisions at sNN =5.02 TeV

The prompt D0 meson azimuthal anisotropy coefficients, v2 and v3, are measured at midrapidity (jyj < 1.0) in Pb-Pb collisions at a center-of-mass energy ffiffiffiffiffiffiffiffi sNN p ¼ 5.02 TeV per nucleon pair with data collected by the CMS experiment. The measurement is performed in the tra...
