Can 'pedestrain' tree level calculation for the gluon emission in 3-jet event provide theoretical understanding of mass-gap and color confinement ?

By the 1950s, when Yang–Mills theory, also known as non-abelian gaugetheory, was discovered, it was already known that Quantum Electrodynamics (QED) gives an extremely accurate account of...

Is there any experimental confirmation regarding the existence of the "Gribov copies" as physical entities in nature ?

“A gauge field describes two dynamical degrees of freedom of a massless spin-1 particle. A most economic description would have been using a two component field. However, to have Lorentz symmetry,...

Is the generalised Coulomb gauge a sole gauge fixing condition leading to propagation of two massless spin 1 degrees of freedom for a masless gluon?

For a massless gluon case, pure QCD field strength is not gauge invariant because of self-interaction of gluons. But the pure QCD Lagrangian gives us gauge invariance and at the same time, gauge...
