Hi
For example in e-e- -> e-e- scattering (electron-electron scattering) the differential cross section goes to infinity as theta goes to zero. Consequently the cross section is infinite.
But how can we measure and interpret the cross section/differential cross section and interpret it as a probability/event rate if it yields infinite values?
This problem DOESN't exist in e-mu- -> e-mu- scattering. What is the fundamental difference between these two processes?
All computations are done to lowest order.
thx
