A cross section is the area over which one particle can collide with another. Things like neutrinos have a low interaction cross section, meaning it is extremely unlikely that another particle will interact with them. It has nothing to do with parallel points or whatever it is you're jabbering about. Check a subatomic physics textbook. |
