Hi Vladyslav,
Oh, I've found that instead of using
DiracTrace[GAD[i1, i2, i3].GA[6].GAD[i5, i6, i7].GA[6],DiracTraceEvaluate -> True];
and
DiracTrace[GAD[i1, i2, i3].((1 + GA[5])/2).GAD[i5, i6, i7].((1 + GA[5])/2), DiracTraceEvaluate -> True],
which leads to two different results, the following two commands result into the same results.
DiracTrace[GAD[i1, i2, i3].GA[6].GAD[i5, i6, i7].GA[6]// DotSimplify // DiracTrick // Simplify,DiracTraceEvaluate -> True];
and
DiracTrace[GAD[i1, i2, i3].((1 + GA[5])/2).GAD[i5, i6, i7].((1 + GA[5])/2)// DotSimplify // DiracTrick // Simplify, DiracTraceEvaluate -> True].
But I'm still not sure how to get the Correct result (I don't want to check each calculation by hand).
Thanks!
Best,
Ya
