| 英文摘要 | The prompt d-0 meson azimuthal anisotropy coefficients, v(2) and ?v(3), are measured at midrapidity ( |y| < 1.0) in pb-pb collisions at a center-of-mass energy root s(nn) = 5.02 tev per nucleon pair with data collected by the cms experiment. the measurement is performed in the transverse momentum (p(t)) range of 1 to 40 gev/c, for central and midcentral collisions. the v(2) coefficient is found to be positive throughout the p(t) range studied. the first measurement of the prompt d-0 meson v(3) coefficient is performed, and values up to 0.07 are observed for p(t) around 4 gev/c. compared to measurements of charged particles, a similar p(t) dependence, but smaller magnitude for p(t) < 6 gev/r, is found for prompt d-0 meson v(2) and v(3) coefficients. the results are consistent with the presence of collective motion of charm quarks at low p(r) and a path length dependence of charm quark energy loss at high p(r), thereby providing new constraints on the theoretical description of the interactions between charm quarks and the quark-gluon plasma. |
