Description

Measurements of production of prompt charm mesons (D0 and D) 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. The prompt charm meson production is measured in minimum bias
p+Pb data, reconstructed via two decay channels: D0->K+pi and
D->D0+pi->K+pi+pi. The production asymmetry between forward and
backward center-of-mass rapidities for the charm mesons is studied for
the range of |y
| < 0.5, and no significant asymmetry is observed. In
the D-hadron correlations, the pT of identified D is more closely
related to the pt of primordial heavy quarks, relative to the
measurement of their decay muons. A finite elliptic harmonic
coefficient for inclusive D* and charge particles have been extracted
with a significance of one to two standard deviations, depending on
multiplicity, broadly consistent with what have been observed for
light hadrons and muons from heavy quark decaying.
