Abstract
We study tracer diffusion in the continuous-time asymmetric random average process which is an interacting particle system on R generalizing the Hamme rsley process. From the equations of motion for the particle-position corre lations we obtain the exact tracer diffusion coefficient which is in agreem ent with a recent heuristic result by Krug and Garcia.
