Production cross sections of light and charmed mesons in e+e- annihilation near 10.58 GeV
Abstract
We report measurements of production cross sections for +, 0, ω, K*+, K*0, φ, η, KS0, f0(980), D+, D0, Ds+, D*+, D*0, and D*+s in e+e- collisions at a center-of-mass energy near 10.58 GeV. The data were recorded by the Belle experiment, consisting of 571 fb-1 at 10.58 GeV and 74 fb-1 at 10.52 GeV. Production cross sections are extracted as a function of the fractional hadron momentum xp . The measurements are compared to pythia Monte Carlo generator predictions with various fragmentation settings, including those that have increased fragmentation into vector mesons over pseudo-scalar mesons. The cross sections measured for light hadrons are consistent with no additional increase of vector over pseudo-scalar mesons. The charmed-meson cross sections are compared to earlier measurements -- when available -- including older Belle results, which they supersede. They are in agreement before application of an improved initial-state radiation correction procedure that causes slight changes in their shapes.
