Here and there some rumors come out about this relevant problem. I have read the following article in Wikipedia http://en.wikipedia.org/wiki/Yang–Mills_existence_and_mass_gap and the talk page http://en.wikipedia.org/wiki/Talk:Yang–Mills_existence_and_mass_gap but people cited there do not seem to be seriously considered as solvers for this question. Mathematics is also quite clear, as understood from the formulation of the problem given by Jaffe and Witten. On the same ground, lattice computations seem to give a sound indication of the existence of the mass gap. So, why no fuss about this question? A recent proposed solution for P vs NP problem has been promptly assessed by the community of mathematicians. Why do not physicists do the same for solutions proposed so far?
