The Quark-Gluon Model Versus the Idea of Partons

Authors: Jean Louis Van Belle

While the reality of quarks has been verified experimentally, we may say that the concept of gluons is more of a mathematical concept. In this paper, we explore the epistemological foundation of quantum chromodynamics. We do so by re-examining the concept of partons, which was introduced by Richard Feynman as a generic term for pointlike constituents of matter. We examine whether or not the concept of a colorless, flavorless and zero-charge parton – onto which we can then load the various properties that are necessary to explain reality – might work. The preliminary conclusion is that the parton model may offer sufficient degrees of freedom to model what the quark-gluon model is modelling. In fact, we suggest the idea of quarks and gluons might be a bit like the 19th century aether theory: perhaps we don’t need it. The underlying question is, of course, much more fundamental: do we need quantum field theory?
