T. Munehisa et al., A PARTON SHOWER MODEL FOR HADRONIC 2-PHOTON PROCESS IN E(-) SCATTERING()E(), Zeitschrift fur Physik. C, Particles and fields, 70(4), 1996, pp. 655-660
A new model of QCD parton shower is proposed which is dedicated to two
-photon processes in e(+)e(-) scattering. When hadron jets are produce
d, the photon may resolve into quark-antiquark pairs so that the struc
ture functions of the photon should be introduced. Based on the Altare
lli-Parisi equation for these functions, an algorithm is formulated th
at allows us to construct a model for parton showers for the photon. O
ur model consists of two parts, one of which describes the deep inelas
tic scattering of the photon and the other one the scattering of two q
uasi-real photons. Using the model some results are presented on parto
n distributions and jet production.
