Bob_for_short Posted June 14, 2011 Share Posted June 14, 2011 (edited) As you know, positrons were predicted theoretically. They were necessary part of the theory and thus were supposed to exist. Often they say that bare particles absorb infinities and this makes the theory work. Some say they are predicted by the theory. I wonder whether somebody has ever been awarded for discovery of bare particles as such? Or this important discovery was left out?

mathematic Posted June 14, 2011 Share Posted June 14, 2011 What are "bare particles"? Positrons certainly exist - PET scanners! Link to comment Share on other sites More sharing options...

ajb Posted June 15, 2011 Share Posted June 15, 2011 Bare particles would be the result of either no interactions or the interactions would not lead to renormalisation. N=4 super Yang-Mills theory requires only wave function renormalsiation so maybe this is the closest to a theory of bare particles? Link to comment Share on other sites More sharing options...
