Triangle Nuclear Theory Colloquium

Adrian Dumitru (Baruch CUNY)

I discuss the structure of longitudinal chromomagnetic fields which

develop in heavy-ion collisions. Rather than being homogeneous, Bz is

found to exhibit domain-like structures in the transverse plane. The

expectation values of spatial Wilson loops exhibit area law scaling

for radii larger than the inverse saturation momentum, indicating

uncorrelated magnetic flux fluctuations at such scales. The

corresponding spatial string tension is approximately invariant

under a Z(2) rotation of the SU(2) Wilson loops. I discuss the

failure of a naive perturbative expansion to reproduce area law

scaling and the role of magnetic screening.
