Are Branched Polymers in the Universality Class of Percolation?
We study the model for branched polymers recently introduced by Lucena et al. [Phys. Rev. Lett. 72, 230 (1994)]. Our calculations of the three exponents dℓ, dmin, and τ for large systems suggest that the model belongs to the universality class of percolation. This is in contrast with the common belief that branched polymers belong to the universality class of lattice animals.
