Abstract

We calculateO s ) corrections to largepT double photon production in hadronic collisions. We find that these corrections to the basic\(q\bar q \to \gamma \gamma \) subprocess are important, preventing to describe double photon production on the basis of the leading logarithm approximation only. We give a phenomenological discussion of the results obtained at SPS, ISR and\(Sp\bar pS\) energies. In particular, we investigate how the effect of the intrinsic parton <KT> may be disentangled from the perturbative contribution. We also calculate the aplanarity distribution characteristic of 3 jet events.
