Abstract

Diffractive dissociation of particles can be used to study their light-cone wave function. Results from Fermilab experiment E791 for diffractive dissociation of 500 GeV/c π^- mesons into di-jets are presented. The results show that the \qq̄) light-cone asymptotic wave function describes the data well for Q² ∼10 (GeV/c)² or more. Evidence for color transparency comes from a measurement of the A-dependence of the yield of the diffractive di-jets. It is proposed to carry out similar studies for the light-cone wave function of the photon.
