Virial corrections to the Boltzmann equation for quasiparticles are obtained from non‐equilibrium Green's functions. These corrections are expressed in terms of shifts in space and time that characterize non‐locality of scattering integrals. The space shifts parallel finite‐diameter corrections to collisions of hard spheres. The time shift is identified as the collision delay. All shifts are given by derivatives of the phase shift in a binary collision.
