We present results on a high statistics study of the proton structure functions F 2 ( x , Q 2 ) and R = σ L / σ T measured in deep inelastic scattering of muons on a hydrogen target. The analysis is based on 1.8 × 10 6 events after all cuts, recorded at beam energies of 100, 120, 200 and 280 GeV and covering a kinematic range 0.06 ⩽ x ⩽ 0.80 and 7 GeV 2 ⩽ Q 2 ⩽260 GeV 2 . At small x , we find R to be different from zero in agreement with predictions of perturbative QCD.

Multiparticle Production by 200-GeV/c Hadrons on Gold, Silver, and Magnesium Targets

We have used the Fermilab 30-in. bubble-chamber hybrid spectrometer to study multiparticle production in the interactions of 200-GeV/c protons and π+ and K+ mesons with nuclei of gold, silver, and magnesium. We find that the multiplicities of produced particles and negative particles increase linearly with the number of projectile collisions, with no beam or target dependence. The number of secondary collisions in the nucleus increases significantly less rapidly with the number of projectile collisions than has been reported by a streamer chamber experiment. The properties of secondary collisions suggest that they arise from rescattering of recoil nucleons rather than intranuclear cascade of produced particles. Dispersions of multiplicity distributions at fixed impact parameter are in better agreement with a model of independent sources than with Koba-Nielsen-Olesen scaling.

Experimental data on multiplicities of secondary charged particles in interactions of oxygen nuclei in a hydrogen bubble chamber at the incident momentum of 3.1 A GeV/c are presented and discussed. Multiplicity correlations are studied in details and it is shown that the character of these correlations is strongly influenced by the electric charge and baryon number conservation. Topologies and probabilities of different channels of fragmentation are determined for projectile oxygen nuclei. It is established that channels with production of helium nuclei play an important role in the processes of multifragment break-up of oxygen nuclei. Comparison of the experimental data with predictions of the cascadefragmentation-evaporation model has shown that the model provide the qualitative description of the considerable amount of experimental observations.

A High Statistics Measurement of the Deuteron Structure Functions F2 (X, $Q^2$) and R From Deep Inelastic Muon Scattering at High $Q^2$

Inspire Record 285497 DOI 10.17182/hepdata.6191

We present results on a high statistics study of the nucleon structure functions F 2 ( x , Q 2 ) and R = σ L / σ T measured in deep inelastic scattering of muons on a deuterium target. The analysis is based on 8×10 5 events after all cuts, recorded at beam energies of 120, 200 and 280 GeV in the kinematic range 0.06⩽ × ⩽0.80 and 8GeV 2 ⩽ Q 2 ⩽260GeV 2 . Scaling violations observed in the data are in agreement with predictions of perturbative QCD and allow to determine the QCD mass scale parameter Λ.
