Production of neutral strange particles in muon-nucleon scattering at 490 GeV
Zeitschrift für Physik C Particles and Fields 61:4 (1994) 539-549
Abstract:
The production of K0, Λ and {Mathematical expression} particles is studied in the E665 muon-nucleon experiment at Fermilab. The average multiplicities and squared transverse momenta are measured as a function of xF and W2. 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 average K0 multiplicity in the forward region favor a strangeness suppression factor s/u in the fragmentation process near 0.20. Clear evidence for QCD effects is seen in the average squared transverse momentum of K0 and Λ particles. © 1994 Springer-Verlag.Measurement of the ratio σn σp in inelastic muon-nucleon scattering at very low χ and Q2

Abstract:
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 Q2>0.01 GeV2. The ratio is consistent with unity throughout this new range. © 1993.An investigation of Bose-Einstein correlations in muon-nucleon interactions at 490 GeV

Abstract:
An investigation of Bose-Einstein correlations amongst like-charged pions produced in muon-nucleon interactions at 490 GeV is presented. On top of a broader enhancement, a steep increase in the correlations at small four-momentum differences between the two pions is observed which may be explained by the contribution from decays of resonances (ρ{variant}-mesons). A two-dimensional analysis discriminates between two different parametrizations of the Bose-Einstein effect, strongly favoring the Lorentz-invariant parametrization over a parametrization based on a Gaussian source distribution in space and time. © 1993.Perturbative QCD effects observed in 490 GeV deep-inelastic muon scattering
