Ridge and Transverse Correlation without Long-Range Longitudinal Correlation
Figure 3
A sketch of initial configuration in - plane at early time. Horizontal thickness of the medium is fm; the inner vertical slab indicates the relative thickness (~0.5 fm) of the overlapping contracted disks in which the valence quarks are restricted. Red arrow represents semihard parton surrounded in medium by a cone of enhanced thermal partons. Blue arrows represent soft partons with GeV/c that originate from outside the slab and can therefore interact with the cone (color online).
