The answer, is of course, [form factors] en.wikipedia.org/wiki/Form_factor_(quantum_field_theory) . Experimentally, you may establish limits on the size of particles through investigation of their form factors, and the size of leptons is always smaller than any scale probed so far, to date, but the size of hadrons is as big as a fermi-sized marshmallow--they are soft and squishy. A good QFT text explains that. | |
