摘要：

Photon-proton (gamma p) interactions with Q(2) < 10(-2) GeV2 and deep-inelastic scattering (gamma*p) interactions with photon virtualities Q(2) > 5 GeV2 are studied at the high energy electron-proton collider HERA. The transverse energy flow and relative rates of large rapidity gap events are compared in the two event samples. The observed similarity between yp and gamma*p interactions can be understood in a picture where the photon develops as a hadronic object. The transverse energy density measured in the central region of the collision, at eta* = 0 in the gamma*p centre of mass frame, is compared with data from hadron-hadron interactions as function of the CMS energy of the collision.
