SUMMARY
The discussion centers on demonstrating the equivalence of calculating the squared amplitude for the quark-antiquark process in lepton-antilepton interactions, considering both non-zero and zero masses of fermions. The user encounters issues with divergent pieces lacking opposite signs during calculations. Additionally, the conversation touches on the implications of squaring negative frequency amplitudes and the validity of negative probabilities in the context of the Schrödinger equation.
