Vector meson and psi contributions to single lepton spectra

The data on the dilepton spectra in a forward cone are used to predict the rho0, ω0, and psi production at theta sub(c.m.) approximately 900 and their contributions to the single lepton spectra. The π, (rho0+ω0), and psi inclusive cross-sections are well fitted over the entire psub(T) range by a simple expression. Combined contributions from rho0, ω0, and psi are found to account for about 30% of the observed lepton spectra. The contribution from the dilepton continuum is also discussed. (Auth.)
