摘要：
The correlation between the two high transverse momentum (pt2.75 GeV/c) photons of the reaction π-p→γγX is studied at the beam momentum of 280 GeV/c. QCD calculations beyond leading logarithms are not sufficient to explain the width of the distributions and the effects due to intrinsic transverse momentum of the incident partons are discussed. © 1990.
