The production ofK0, Λ and\(\bar \Lambda \) particles is studied in the E665 muon-nucleon experiment at Fermilab. The average multiplicities and squared transverse momenta are measured as a function ofxF andW2. Most features of the data can be well described by the Lund model. Within this model, the data on the K0/π± ratios and on the averageK0 multiplicity in the forward region favor a strangeness suppression factors/u in the fragmentation process near 0.20. Clear evidence for QCD effects is seen in the average squared transverse momentum ofK0 and Λ particles.

Measurement of the ratio sigma(n) / sigma(p) in inelastic muon - nucleon scattering at very low x and Q**2

The E665 collaboration Adams, M.R. ; Aïd, S. ; Anthony, P.L. ; et al.
Phys.Lett.B 309 (1993) 477-482, 1993.
Inspire Record 354238 DOI 10.17182/hepdata.28907

We present results on the cross-section ratio for inelastic muon scattering on neutrons and protons as a function of Bjorken chi;. The data extend to χ values two orders of magnitude smaller than in previous measurements, down to 2×10 −5 , for Q 2 >0.01 GeV 2 . The ratio is consistent with unity throughout this new range.
