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。 -
