Abstract:
We use classical equations of motion for heavy quarks to show that the preequilibrium glasma phase of a heavy ion collision has an extremely strong effect on heavy quark angular correlations. At the same time the effect on the single inclusive spectrum is much more moderate. This suggests that DD[over ¯] meson angular correlations in future LHC measurements could provide a direct experimental access to the physics of the preequilibrium stage.
