Abstract
We derive the short distance interaction of star polymers in a colloidal solution. We calculate the corresponding force between two stars with arbitrary numbers of legs f1 and f2. We show that a simple scaling theory originally derived for high f1, f2 nicely matches with the results of elaborated renormalization group analysis for f1 + f2 =< 6 generalizing and confirming a previous conjecture based only on scaling results for f1=f2=1,2.
