The gauge invariant QCD Lagrangian is4a311a4a1d3ddae8fd71810cd92ba15f.pngwhere is the quark field, are the Dirac matrices, are the 8 gauge fields, and are the generators of the SU(3) group. The term labeled is similar to the Electromagnetic tensor, , found in Quantum electrodynamics. therefore the answer isfc2e7b21949624c98a24a11f661b3718.pngQ.E.D.
Damn, i was thinking that biggrin.gif
well you can still find out the value if the electromagnetic tensor is halved, and what will the value of 8 then be.
