Heavy flavor angular correlations as probes of the glasma

We study the effect of the glasma fields, formed in the early stage of heavy-ion collisions, on the transport of QQ̅ pairs produced back-to-back. We find that for pairs with moderate initial transverse momentum pT evolving in glasma fields with sufficiently large saturation momentum Qs, the azimuthal correlation C(Δφ) is quickly affected. The decorrelation widths σΔϕ during the glasma and Quark Gluon Plasma (QGP) phases are comparable.

Abstract

We study the effect of the glasma fields, formed in the early stage of heavy-ion collisions, on the transport of QQ̅ pairs produced back-to-back. We find that for pairs with moderate initial transverse momentum pT evolving in glasma fields with sufficiently large saturation momentum Qs, the azimuthal correlation C(Δφ) is quickly affected. The decorrelation widths σΔϕ during the glasma and Quark Gluon Plasma (QGP) phases are comparable.
