We consider one-dimensional asymmetric zero-range proce sses starting from a step decreasing profile leading, in the hydrodynamic limit , to the rarefaction fan of the associated hydrodynamic equation. Under that initial cond ition, and for totally asymmetric jumps, we show that the weighted sum of joint probabilities for sec ond class particles sharing the same site is convergent and we compute its limit. For partially asymmetric jumps, we derive the Law of Large Numbers for a second class particl e, under the initial configuration in which all positive sites are empty, all nega tive sites are occupied with infinitely many first class particles and there is a single sec ond class particle at the origin. Moreover, we prove that among the infinite characteristics e manating from the position of the second class particle it picks randomly one of them. The r andomness is given in terms of the weak solution of the hydrodynamic equation, through s ome sort of renormalization function. By coupling theconstant-rate totally asymmetric zero-range with the totally asymmetric simple exclusion, we derive limiting laws for mo re general initial conditions.
