• 論文の詳細を見る

• The validity of a photon shower generator QEDPS is examined in detail. This is formulated based on the leading-logarithmic renormalization equation for the electron structure function and it provides a photon shower along the initial e^±. The main interest in the present work is to test the reliability of the generator to describe a process accompanying hard photons which are detected. For this purpose, by taking the HZ^0 production as the basic reaction, the total cross section and some distributions of the hard photons are compared for the two cases that these photons come from either those generated by QEDPS or the hard process e^+e^- ⇾ HZ^0 γ…γ. The comparison performed for the single and the double hard photon yields satisfactory agreement, demonstrating that the model is self-consistent.
