Resumen
We investigate the transition from the nucleon-meson to the quark-gluon description of the strong interaction using the photon energy dependence of the d(γ, p)n differential cross section for photon energies above 0.5 GeV and center-of-mass proton angles between 30° and 150°; A possible signature for this transition is the onset of cross-section s-11 scaling with the total energy squared, s, at some proton transverse momentum PT. The results show that the scaling has been reached for proton transverse momentum above about 1.1 GeV/c. This may indicate that the quark-gluon regime is reached above this momentum.
