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
