Branched Polymers and Percolation
  We study a supposed model for branched polymers which was shown in two dimensions to be in the universality class of ordinary percolation. We confirm this by high statistics simulations and show that it is in the percolation universality class also for three dimensions, in contrast to previous claims. These previous studies seem to have been mislead by huge corrections to scaling in this model.
