摘要
We generalize Witten's calculation of the photon structure function F2γ to the next-to-the-leading order of asymptotic freedom. Except for the second moment of F2γ, the result is independent of the unknown matrix elements of quark and gluon operators between the photon states. The nonleading corrections turn out to be large. © 1979 The American Physical Society.
