Charged Hadron Multiplicities in 400-GeV Deep Inelastic Muon Scattering
- Maryland U.
In this thesis, the multiplicity of charged hadrons produced in deep inelastic muon-nucleon scattering was studied using a 490 Gev muon beam impinging upon liquid hydrogen and liquid deuterium targets. Multiplicity was measured using a streamer chamber and forward wire tracking chambers. Muon kinematics were obtained by beam tracking upstream of the target and identification of the scattered muon in the forward detectors. The multiplicity distributions and average multiplicity for $$H_2$$ and $$D_2$$ were found to be consistent with each other both qualitatively and quantitatively. This result supports the statement that sea quark scattering dominates as one would expect from the fact that more than 90% of the data is in the $$x_{B_j}$$ < .2 region. Agreement between the data and the Lund Monte Carlo generated with Morfin and Tung structure functions was observed. This result supports t.he assumption in that model that up to 50% of the DIS data. is photon-gluon fusion.
