The infrared problem in quantum chromodynamics is studied in order to elucidate aspects of high energy behavior. The integro-differential equation of Cornwall and Tiktopoulos is used to investigate quark-quark scattering in the limit λ → 0 (λ being the gluon regulator mass), s → ∞ with t fixed. The solution displays the infrared factors explicitly. When this formula is expanded in power series and the leading ℓog is extracted one recovers the perturbation theory calculations to sixth order. Having argued that the infrared singular terms in the equation are independent of the renormalization mass M, asymptotic freedom can be used to evaluate the remainder. Some remarks are made on the scattering of color-singlet quark clusters with a view towards solving the physical problem.

    The perturbation results were given in the case of a local SU2 gauge symmetry. In our approach it is elementary to change from SU2 to SU3. Google Scholar

    The results of refs. 2–4 were given in terms of certain integrals K.(t). We have evaluated these integrals for small X in order to compare with our equations.Google Scholar
