Production cross sections of light and charmed mesons in e+e- annihilation near 10.58 GeV
Original language description
We report measurements of production cross sections for rho(+), rho(0), omega, K*+, K-*0,phi,eta, K-S(0), f(0) (980), D+, D-0, D-s(+), D*+, D-*0, and D-s(*+) 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 x(p). The measurements are compared to PYTHIA Monte Carlo generator predictions with various fragmentation settings, including those that have increased fragmentation into vector mesons over pseudoscalar mesons. The cross sections measured for light hadrons are consistent with no additional increase of vector over pseudoscalar 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 x(p) shapes.
