M. Batista et al., DESCRIPTION OF INCLUSIVE MESON SPECTRA IN E(-) ANNIHILATION REACTIONSBY A QUARK CASCADE MODEL()E(), Progress of theoretical physics, 98(3), 1997, pp. 661-676
We present a model to describe inclusive meson production in e(+)e(-)
reactions based on a quark cascade approach whose formulation is put i
n terms of diffusion equations for three quark flavors (u, d, s). Thes
e equations are solved by using a formalism previously developed for t
he problem of the electromagnetic cascade generated in the atmosphere
by cosmic-ray interactions. The obtained solutions are given in terms
of a combination of power-law functions whose profiles are adequate to
describe the characteristics observed in the inclusive spectrum of me
sons.
