ρ0 andω production in deep inelastic μ-p interactions at 280 GeV/c

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.
