摘要
Measurements of transverse energy flow are presented for neutral current deep-inelastic scattering events produced in positron-proton collisions at HERA. the kinematic range covers squared momentum transfers Q(2) from 3.2 to 2 200 GeV2. the Bjorken scaling variable x from 8 . 10(-5) to 0.11 and the hadronic mass W from 66 to 233 GeV. The transverse energy flow is measured in the hadronic centre of mass frame and is studied as a function of Q(2). x, W and pseudorapidity. A comparison is made with QCD-based models. The behaviour of the mean transverse energy in tbe central pseudorapidity region and an interval corresponding to the photon fragmentation region are analysed as a function of Q(2) and W.
