Azimuthal correlations of D-mesons in + and +Pb collisions at LHC energies
We study the correlations of D mesons produced in + and +Pb
collisions. These are found to be sensitive to the effects of the cold nuclear
medium and the transverse momentum () regions we are looking into. In
order to put this on a quantitative footing, as a first step we analyse the
azimuthal correlations of D meson-charged hadron(Dh), and then predict the same
for D meson -anti D meson () pairs in + and +Pb
collisions with strong coupling at leading order ()
and next to leading order () which includes space-time
evolution (in both systems), as well cold nuclear matter effects (in +Pb).
This also sets the stage and baseline for the identification and study of
medium modification of azimuthal correlations in relativistic collision of
heavy nuclei at the Large Hadron Collider.Comment: 12 pages, 4 figure
