D meson production and long-range azimuthal correlation in 8.16 TeV p+Pb collisions with ATLAS

Measurements of prompt charm mesons ($D^0$ and $D^*$) productions and azimuthal correlations between inclusive $D^*$ and charged particles are presented in p+Pb collisions data at 8.16 TeV collected in 2016 by ATLAS. No significant production asymmetry between forward and backward and asymmetry is observed. A finite $2\cos(2\Delta\phi)$ modulation for inclusive $D^*$ is observed with a $1\sim2\sigma$ significance, depending on multiplicity, broadly consistent with what have been observed for light hadrons and HF muons.
