Which devices will create multiple collision domains in an ethernet network 哪些裝置將會(huì)在一個(gè)乙太網(wǎng)絡(luò)網(wǎng)絡(luò)中產(chǎn)生多樣的碰撞領(lǐng)域
In p - a drell - yan process , the incident quark will experience multiple collisions with different nucleons in the nucleus , which leads to the suppressed drell - yan cross section , in another words , the nuclear shadowing effect 在靶靜止系,對(duì)于p - a碰撞的drell - yan過程,入射夸克要與原子核中的不同核子發(fā)生多次碰撞,使得總的微分截面被壓低,這就是遮蔽效應(yīng)。
Gribov combined the nonrelativistic glauber multiple collisions theory with quantum field theory and fe ynman diagram technique so that relativistic kinematics could be included . based on glauber - gribov theory , b . z . kopeliovich et . al . developed green function method to calculate the shadowing effect in p - a drell - yan process Gribov將描述高能非相對(duì)論的多次碰撞的glauber理論與量子場(chǎng)論和費(fèi)曼圖聯(lián)系了起來,從而glauber - gribov理論可以描述相對(duì)論情況下的多次散射,基于這一理論, b . z . kopeliovich等提出用格林函數(shù)方法計(jì)算p - a碰撞的drell - yan過程中的遮蔽效應(yīng)。
