Abstract
Photon-proton (gamma p) interactions with Q(2) < 10(-2) GeV2 and deep- inelastic scattering (gammap) interactions with photon virtualities Q (2) > 5 GeV2 are studied at the high energy electron-proton collider H ERA. The transverse energy flow and relative rates of large rapidity g ap events are compared in the two event samples. The observed similari ty between yp and gammap 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 i n the gammap centre of mass frame, is compared with data from hadron- hadron interactions as function of the CMS energy of the collision.
