The large-time small-mass asymptotic behavior of the average mass distribution (P) over bar (m,t) is studied in a d-dimensional system of diffusing aggregating particles for 1less than or equal todless than or equal to2. By means of both a renormalization group computation as well as a direct resummation of leading terms in the small-reaction-rate expansion of the average mass distribution, it is shown that (P) over bar (m,t)similar to(1/t(d))(m(1/d)/roott)(e)(KR) for m<<t(d/2), where e(KR)=epsilon+O(epsilon(2)) and epsilon=2-d. In two dimensions, it is shown that (P) over bar (m,t)similar toln(m)ln(t)/t(2) for m<<t/ln(t). Numerical simulations in two dimensions supporting the analytical results are also presented.
