We numerically study shear-induced diffusion of soft athermal particles intwo dimensions. The Green-Kubo (GK) relation is applicable to diffusioncoefficient of the particles near jamming, where both mean squared particlevelocities and relaxation time included in the GK formula are well explained bycritical scaling. We show that auto-correlation functions of the transversevelocities are stretched exponential if the system is below jamming or shearrate is large enough. However, if the system is above jamming and the shearrate is sufficiently small, the auto-correlations exhibit long-time tails suchthat time integral in the GK formula diverges in two dimensions. We proposeempirical scaling relations for the critical exponents and demonstrate that thelong-time tails cause finite size effects on the shear-induced diffusioncoefficient.
