Due to the repulsive coulomb field, the effective impact parameter increases, and therefore the calculated reaction cross section decreases
庫侖場的排斥效應使得核?核反應有效的碰撞參數增大,使計算的反應截面減小,同時這種修正的效應隨能量增大而減小。The transverse expansion origins in early stages, but mainly develops and finishes during the late stage of the colliding. for those heavier particles, such as j /, e, and etc., becuase of their smaller hadronic cross section, they rarely participate the final state hadronic re - scattering, and depart the system much earlier. their transverse expansion maybe is the result of the cumulative collective effect during the early partonic stage
這種橫向擴張起源於碰撞的初始階段,但是主要是在碰撞的後期完成,而一些重的粒子,如j 、和,由於具有較小的強子散射截面,幾乎不參與末態強子的再散射,較早的離開碰撞系統,它們所表現出來的橫向擴張運動可能是來自碰撞初期部分子階段的部分子的集體效應的累積結果。
