This is a topic that I have tried researching and I have not been able to find any meaningful information about it. The standard model of particle physics describes particles as point-like objects with no spatial extent. What I can't wrap my head around is how true point particles can participate in interactions. If particles did not have cross-sections, then they would simply fly past one another and not interact at all (i.e. the probability of an interaction would be infinitesimal). Is there any explanation as to how point particles like electrons or quarks or neutrinos can have non-zero cross sections?
I don't know if standard particle physics is enough to answer this question. If concepts relating to QFT or other areas of physics are required, then the Mentors are free to move this thread to the appropriate forum.
