Description

Within the light-cone path integral approach the effect of the induced gluon radiation on high-pT hadrons in high-energy heavy-ion collisions is studied. The induced gluon spectrum is represented in a new form which is convenient for numerical simulations. For the first time computations are performed with a realistic parametrization of the dipole cross sections. The results are in reasonable agreement with suppression of high-pT hadrons in Au + Au collisions at 200 GeV

Abstract (Russian)

В рамках интегрального подхода для светового конуса изучается влияние индуцированного глюонного излучения на адроны с высоким pT в столкновениях тяжелых ионов при высокой энергии. Полученный глюонный спектр представлен в новой форме, удобной для компьютерного моделирования. Впервые выполнены расчеты с реалистической параметризацией дипольного сечения. Полученные результаты согласуются с подавлением образования адронов с высоким pT в столкновениях Au + Au, измеренным при 200 ГэВ
