parton model 中文意思是什麼
-
The knowledge of these initial collision is crucial for any theoretical treat - ment of a possible parton - hadron phase transition, the detection of which being the ultimate aim of all the efforts of co1liding heavy ions at very high energies. the parton model allows to calculate inclusive cross sections as a convolution of any elementary cross section with parton distribution functions, assuming that factorization works. the disadvantage is that tlle first interaction is coilsidered quite differently from the subsequent ones in case of multiple scattering
其它的弦模型在計算幾率時，忽略了入射能量在pomeron之間的分配，破壞了能量守恆，而且把pomeron作為全同粒子處理，即pomeron之間是不可區分的；然而在處理粒子產生時，這些模型雖然考慮了能量守恆，但是第一個pomeron的粒子產生與其它的pomeron很不一樣? ? pomeron在粒子產生時不是全同的。 -
The lund string dynamical model frifiof, luciae model and jpciae model were introduced in the third chapter. luciae model is based on frifiof model, while jpciae model is based on pyth1a. paciae model, a new model based on parton and hadron cascade is being improved and its physical ideas is introduced
論文的第三章主要介紹了建立在lund弦模型基礎上的強子和d玄級聯的fritiof模型、 luciae模型和jpciae模型，其中luciae模型是建立在frjtiof棋型的基礎上，而jpciae模型是建立在pythia的基礎之上的。 -
The simplest form of the parton and hadron cascade model, paciae1. 0, is employed to investigate the charge fluctuation of quark matter and the pauli blocking at the partonic stage of ultra - relativistic nucleus - nucleus collisions and its effect on the hadronic final state
完整部分子和強于級聯模型， paciae還在進一步的完善之中，我們對其物理思想作了較為詳細的介紹，簡單的部分子模型paciaei刀己用來研究電荷漲落和pauli阻塞等問題。當s jeon 、 v
