Ken Kawarabayashi, +1 more
- 07 Feb 1966 - 
TL;DR: The notion of partially conserved axial-vector current (1) (PCAC) and the current commutation relations that generate the algebra U(2)xU (2) have been successfully applied to the calculation of the axial vector constant renormalization and to the non-leptonic decays of hyperons and K mesons.

Frequently Asked Questions (1)
Q1. What have the authors contributed in "In this paper we shall show how the operator product expansion links-together two critical testing grounds of quantum chromodynamics (qcd> : the evolution of the moments of the deep inelastic structure functions and the short distance structure of the hadronic wave functions which appear in large momentum transfer exclusive reactions. in parti- cular, we shall be able to relate the anomalous dimension y, of the n-th non-singlet operator that appears in the description of deep inelastic lepton-hadron scattering to a corresponding logarithmic correction" ?

In this paper, the anomalous dimension of the non-singlet structure functions is compared to a corresponding logarithmic correction factor to the nominal as ( Q2 ) /Q2 fall off of meson form factors.
