| contents | We study the effect of the glasma fields, formed in the early stage of heavy-ion collisions, on the transport of $Q\bar{Q}$ pairs produced back-to-back. We find that for pairs with moderate initial transverse momentum $p_T$ evolving in glasma fields with sufficiently large saturation momentum $Q_s$, the azimuthal correlation $C({Δϕ})$ is quickly affected. The decorrelation widths $σ_{Δϕ}$ during the glasma and Quark Gluon Plasma (QGP) phases are comparable. |
