Abstract Inclusive momentum and energy spectra of neutral and charged D-mesons produced in e+e− annihilation at energies near 7 GeV are presented. The slope of the energy spectrum is similar to the charged pion spectrum at the same energy. The inclusive cross section σ(e+e−→ D or D + anything) at 7 GeV is 4.8±1.3 nb.

We have measured inclusive ..gamma.. and ..pi../sup 0/ production in multiprong events produced by e/sup +/e/sup -/ annihilation in the center-of-mass energy range 4.9 to 7.4 GeV. We find that ..pi../sup 0/ inclusive cross section to be consistent in shape and normalization with half the charged-..pi.. cross section between chi = 0.15 and 0.60, with an integrated inclusive cross-section ratio of sigma (..pi../sup 0/)/ vertical-bar (sigma (..pi../sup +/) + sigma (..pi../sup -/) vertical-bar = 0.47 +- 0.10.

Abstract In e + e − annihilations at SPEAR we have searched for narrow neutral resonances in the eπ and μπ channels for masses between 0.5 GeV/ c 2 and 1.5 GeV/ c 2 . No evidence for such states has been found. Under standard theoretical assumptions for production cross sections and decay branching ratios of heavy leptons a lower limit of 1.2 GeV/ c 2 can be set on the mass.

Abstract We present measurements of the cross section for inclusive D and K meson production in e+e− annihilation in the center of mass energy range 3.6 to 5.8 GeV. D production accounts for most of the increase in the total cross section for hadron production in e+e− annihilation at energies above 4 GeV.
