The proton structure function F 2 has been measured in the range 2.5 ⪕ Q 2 ⪕ 170 GeV 2 and 0.03 ⪕ x ⪕ 0.65 . Scaling violation is clearly seen in the data. Results of fits to leading-order QCD are presented, together with values of the scale-breaking parameter λ.

Forward Produced Protons and Anti-protons in Deep Inelastic Muon Proton Scattering

The European Muon collaboration Aubert, J.J. ; Bassompierre, G. ; Becks, K.H. ; et al.
Phys.Lett.B 103 (1981) 388, 1981.
Inspire Record 166178 DOI 10.17182/hepdata.31185

A significant rate of forward proton and antiproton production has been observed in 120 and 280 GeV muon-proton scattering. The z and p T 2 distributions are presented. The dependence of the normalized production cross section on the muon variables x and Q 2 is studied.

Transverse momentum of charged hadrons observed in deep inelastic muon scattering

The European Muon collaboration Aubert, J.J. ; Bassompierre, G. ; Becks, K.H. ; et al.
Phys.Lett.B 95 (1980) 306, 1980.
Inspire Record 154081 DOI 10.17182/hepdata.27176

The transverse momenta of charged hadrons produced in high energy muon-proton scattering have been studied. The average squared transverse momentum 〈 p 2 ⊥ 〉 shows a strong dependence on z = E h / v characteristic of intrinsic momentum effects and a significant rise as a function of s = W 2 . The W 2 , q 2 , x and z dependences of the data are compared with the predictions of a perturbative QCD model.

MEASUREMENTS OF SHADOWING IN LOW Q**2 ELECTROPRODUCTION ON NUCLEI

Bailey, J. ; Botterill, D.R. ; Montgomery, Hugh E. ; et al.
Nucl.Phys.B 151 (1979) 367-388, 1979.
Inspire Record 132234 DOI 10.17182/hepdata.34763

Measurements of inelastic electron scattering have been made in the range 2.2 < ν < 3.8 GeV and 0.1 < | Q 2 | < 0.3 (GeV/ c ) 2 , on a selection of nuclei ranging from hydrogen and deuterium to uranium, by measuring the scattered electron only. Detailed calculations have been made of the contribution of radiative tails to the measured yield. The results show a small ‘shadowing’ consistent with other electroproduction experiments, and also with photoproduction experiments in this ν range, but the shadowing decreases rapidly as | Q 2 | increases.

A Study of Inclusive xi- Production from K- p Interaction at 4.2-GeV/c

The Amsterdam-CERN-Nijmegen-Oxford collaboration Ganguli, S.N. ; Berge, J.P. ; Gavillet, P. ; et al.
Nucl.Phys.B 128 (1977) 408-420, 1977.
Inspire Record 111753 DOI 10.17182/hepdata.36076

A study of inclusive Ξ − production from a high statistics K − p experiment at 4.2 GeV/ c has been made. The total Ξ − production cross section is 157 ± 8 μ b. Approximately 15% of the Ξ − arise from decay of the Ξ ∗0 (1530) resonance. The polarization of the Ξ − is found to be negative and is nearly equal in value to that of the Λ 0 from the inclusive reaction K − + p → Λ 0 + anything. An analysis of the inclusive production of Ξ − has been made in the framework of the triple-Reege formalism.
