    • Abstract

       

      We consider the effects of quark masses to the perturbative thrust in e+e annihilation. In particular we show that perturbative power corrections resulting from non-zero quark masses considerably alters the size of the non-perturbative power corrections and consequently, significantly changes the fitted value of αs.
