SU(2). beta. function with and without dynamical fermions

· Phys. Rev. Lett.; (United States)
We study the ..beta.. function of SU(2) lattice gauge theory in the presence and absence of dynamical fermions with the (improved) ''ratio method.'' The pseudofermion algorithm used to simulate the fermion action seems to be capable of giving the right contribution to the ..beta.. function. For two flavors of fermions we find agreement with asymptotic scaling to within approx.15% for ..beta..> or approx. =2.0
