We calculate analytically the dynamic critical exponent zMC, measured in Monte Carlo simulations for a vortex loop model of the superconducting transition, and account for the simulation results. In the weak screening limit, where magnetic fluctuations are neglected, the dynamic exponent is found to be zMC = 3/2 . In the perfect screening limit, zMC = 5/2 . We relate zzMC to the actual value of z observable in experiments and find that z ∼ 2, consistent with some experimental results.
