Influence of Interference Terms on Probability of Color Connections among Partons in e+e－→qq+ng Process

  • Large Nc approximation is adopted in popular e+e－ event generators where the production probability of singlet chain states is 100% and that of color separate states is 0. In the real world Nc=3, we investigate the origin and character of color and kinematics aspects in interference terms. We find that the production probability of color singlet chain states decreases from 83%, 77% to 67%, 58% for qq+2g and qq+3g system respectively after considering the interference terms. Especially, the production probability of color separate states increases to twice of that without interference terms for qq+2g. Hence when n is larger, we can expect that the production probability of singlet chain states will be far less than 1 and that of color separate states will significantly increase when n is larger.

Abstract: Large Nc approximation is adopted in popular e+e－ event generators where the production probability of singlet chain states is 100% and that of color separate states is 0. In the real world Nc=3, we investigate the origin and character of color and kinematics aspects in interference terms. We find that the production probability of color singlet chain states decreases from 83%, 77% to 67%, 58% for qq+2g and qq+3g system respectively after considering the interference terms. Especially, the production probability of color separate states increases to twice of that without interference terms for qq+2g. Hence when n is larger, we can expect that the production probability of singlet chain states will be far less than 1 and that of color separate states will significantly increase when n is larger.
