Is the strong-coupling constant small
Description
It is important to examine the strong-coupling parameter Λ in deep-inelastic scattering, since (e.g.) the proton lifetime in grand-unified theories is quite sensitive to Λ. We show that Λ is not as small in μN scattering as previously reported. Furthermore, Λ extracted from F2(x, Q2) is highly correlated with the parameterization of the gluon distribution. Other problems arise from sigmasub(L)/sigmasub(T) assumptions. (orig.)
