Forward muon detection in H1 and hadronic energy flow in deep inelastic scattering
Abstract
The H1 experiment observes collisions between 26.7 GeV electrons and 820 GeV protons which are accelerated in the HERA storage ring at DES Y in Hamburg. High energy muons at small angles to the incoming proton direction are detected in the forward muon detector, a drift chamber system incorporating its own toroidal magnet which allows it to make independent momentum measurements. This detector is described and its potential for use in the context of identifying J/psi mesons via their decay to two muons is assessed using computer simulations. It is shown that the forward muon detector can be used to identify muons in the central tracking detectors of H1. In the first year of operation, 1992, data corresponding to an integrated luminosity of about 25 nb-1 were collected including about 1000 neutral current deep inelastic scattering events. A measurement of the hadronic energy flow seen in H1 for these events is made and compared with monte carlo predictions based on various models of the perturbative QCD processes involved. None is found to satisfactorily reflect the data in the kinematic region of Bjorken x between 10-4 and 10-3.
