Abstract

Inclusive distributions of ρ0 and ω mesons have been measured in deep inelastic μ-p interactions at 280 GeV/c. A comparison of the ρ0 cross sections with other leptoproduction experiments is presented. The ω results represent the first observation of this inclusive channel in high energy leptoproduction. The ρ0 and ω yields are found to be equal as may be expected from the available density of states in isospin space. This contrasts with spin angular momentum where the vector to pseudoscalar meson ratio is suppressed relative to the available number of spin states.

Abstract

A study of the distribution of the azimuthal angle ϕ of charged hadrons in deep inelastic μ−p scattering is presented. The dependence of the moments of this distribution on the Feynmanx variable and the momentum transverse to the virtual photon indicates that non-zero moments arise mainly from the effects of the intrinsicK T of the struck quark with >≳(0.44 GeV)2, and to a lesser extent from QCD processes. No significant variation withQ 2 orW 2 is observed.

Abstract

The Bose-Einstein correlation has been observed for pions in deep inelastic μp interactions at 280 GeV. The importance of non-interference correlations in the sample of like charge pion pairs and in the sample used for reference is discussed. The pion emission region is found to be roughly spherical in the pair rest frame with a radius of 0.46–0.84 fm and the chaos factor λ is 0.60–1.08.
