INCLUSIVE SPECTRA OF CHARGED HADRONS FROM psi AND psi-prime DECAYS

The inclusive charged-hadron momentum spectra from the ψ and ψ′ decays produced in e+e− 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+e− collisions at s=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.

Inclusive Hadron Production in $e^+ e^-$ Annihilation at $\left\langle s\right\ranlge = 53$-{GeV}$^2$

Aschman, D. ; Coyne, D.G. ; Groom, Donald E. ; et al.

We report on inclusive hadron production in e+e− annihilation at 〈s〉=53 GeV2, using a small solid-angle magnetic spectrometer with good particle identification at 90° to the beams at SPEAR II. The cross sections of π± and K± when compared with data at s=23 GeV2 exhibit scaling in (sβ)dσdx with x=2Es12. The invariant cross section depends on the momentum as p−4.
