| dc.description.abstract | We calculate the critical value of the hopping parameter, κc , in lattice QCD with Wilson fermions, to two loops in perturbation theory. This quantity is an additive renormalization | en |
| dc.description.abstract | as such, it is characterized not only by the standard caveats regarding the asymptotic nature of perturbative results, but also by a linear divergence in the lattice spacing. Consequently, our calculation tests rather stringently the limits of applicability of perturbation theory. We compare our results to non-perturbative evaluations of κc coming from Monte Carlo simulations. Finally, we apply a tadpole improvement technique to our results | en |
| dc.description.abstract | this shifts them quite favorably towards the nonperturbative values. ©2000 The American Physical Society. | en |
