Recently Altarelli, Curci, Martinelli, and Petrarca have calculated the second order corrections induced by quantum chromodynamics to the effective weak Hamiltonian in Δc = 1 processes. We extend their analysis by including the effects of the heavy t and b quarks. The technique used is that first introduced by Witten to study the effects of heavy quarks in deep inelastic scattering and used by Gilman and Wise and Guberina and Peccei to discuss how quark masses alter the effective weak Hamiltonian to leading order in [Formula: see text] processes.

Fit of gluon self-coupling suggested by E. Reya1 is made in Quantum Chromodynamics for three (n=3, 4, 5) moments of the gluon distribution in the region of Q2~ 50–1000 GeV 2. The result depends strongly on the parametrization of the ratio R(x, Q2) =σL/σT, where σL and σT are cross sections of the longitudinal and transverse photon on a nucleon. We show the necessity of the logarithmic rather than power violation of the Callan-Gross correlation.2
