CONFORMATION-SPACE RENORMALIZATION OF RANDOMLY BRANCHED POLYMERS

We present a renormalization group theory in polymer conformation space to describe randomly branched polymers in which monomers interact with each other through the excluded volume interaction. We make a perturbation expansion for the mean square radius of gyration of randomly branched polymers with annealed structures and identify the appropriate scaling variable. We further perform a renormalization group analysis that results in the epsilon expansion for the critical exponents of the radius of gyration nu=1/4+epsilon/36 and of the number of configurations theta=5/2-epsilon/12, which are consistent with the re- sults of an earlier theory.
