Abstract
We present novel insights into the elusive f0(980) hadron’s quark composition and the interaction of heavy charm quarks with the quark-gluon plasma (QGP) through the anisotropic flow measurement of D0 in Heavy-Ion collisions. The f0(980), whose precise configuration has remained controversial, is reconstructed for the first time via its dominant decay channel, f0(980) → π+π−, using data from proton-lead collisions at 8.16 TeV, as collected by the CMS experiment. The azimuthal angle anisotropy v2 of f0(980) relative to the event plane is also investigated, allowing us to extract the v2 parameter for the f0(980) and compare it with other hadrons. In addition, we also investigate how heavy quarks interact with QGP by measuring the coefficients of azimuthal anisotropy (vn)ofD0 mesons in lead-lead collisions at 5.02 TeV with CMS experiment. The measurements cover a wide range of transverse momentum and thus reveal the flow formation mechanisms of heavy charm quarks, illuminating the diffusion and path-dependent parton energy loss.
