a study on the energy rule for the identification of gluon and quark jets 辨別膠子噴注和夸克噴注的能量法則研究
in order to study the dynamical fluctuations inside the gluon jets and quark jets, the improved angular rule is proposed to identify these tv / o kinds of jets from the 3-jet events 為了進(jìn)一步研究3-噴注事件中的夸克(反夸克)噴注和膠子噴注內(nèi)部的動(dòng)力學(xué)起伏的性質(zhì)
this thesis studied the dynamical fluctuations inside the single jets in 2-jet events and the quark and gluon jets in 3-jet events carefully to explore the dynamics of strong interaction . the dynamical fluctuations inside the single-jets, the quark jets aad antiquark jets are studied using monte carlo method respectively 本文對(duì)e~+e~-碰撞產(chǎn)生的2-噴注事件中的單噴注子樣本和3-噴注事件中的夸克噴注及膠子噴注子樣本內(nèi)部的動(dòng)力學(xué)起伏進(jìn)行仔細(xì)地研究
based on the above analysis, the dynamical fluctuations inside the gluon jets and ( mark jets are investigated separately using monte carlo method . the results show that the properties of dynamical fluctuations inside the quark jets in the 3-jct events is the same as that in the 2-jet events . while in the 3-jet events the dynamical fluctuations in pt direction inside quark jets is stronger than that inside gluon jets indicating the fragmentation dynamics in these two kinds of jets is quite different 從而證明了用改進(jìn)的角度法則s髓成功地從3噴注事件中拄瞼出馳,反中克和膠介吹注米?在以上研究的基礎(chǔ)上,本文對(duì)用改進(jìn)的角度腳栩隧出來(lái)的夸克賬和膠子哪內(nèi)部的動(dòng)力學(xué)起伏進(jìn)行廠mon比carlo研究?結(jié)果顯示,3噴注事件中的夸克噴注和噴注事件中的夸克噴注內(nèi)部有完全相同的動(dòng)力學(xué)起伏性質(zhì)
