Inclusive spectra of charged hadrons from ψ and ψ ′ decays

The inclusive charged-hadron momentum spectra from the psi and psi' decays produced in e/sup +/e/sup -/ collisions at SPEAR are presented. The data were obtained with a small solid-angle, single-arm magnetic spectrometer with good particle-identification abilities centered at 90 degrees with re...

Zusammenfassung:The inclusive charged-hadron momentum spectra from the psi and psi' decays produced in e/sup +/e/sup -/ collisions at SPEAR are presented. The data were obtained with a small solid-angle, single-arm magnetic spectrometer with good particle-identification abilities centered at 90 degrees with respect to the beams. The particle-separated invariant cross sections are compared with data from e/sup +/e/sup -/ collisions at ..sqrt..s-bar = 4.8 and 7.3 GeV, obtained with the same spectrometer, in order to observe the difference between hadron production at the resonances and in the continuum.
