โœฆ Synopsis

Deep-inelastic scattering events with a leading baryon have been detected by the H1 experiment at HERA using a forward proton spectrometer and a forward neutron calorimeter. Semi-inclusive cross sections have been measured in the kinematic region 2 _< Q2 ~ 50 GeV 2, 6-10 -5 < x < 6.10 -a and baryon pT _< 200 MeV. A Regge model of leading baryon production which consists of pion, pomeron and secondary reggeon exchanges gives an acceptable description of both semi-inclusive cross sections in the region 0.1 _< x~ ~ 0.3. The leading neutron data are used to estimate the structure function of the pion at small Bjorken-x.
