Hi,

How are gamma matrices defined in Feyncalc?

Becouse in a standard definition (the one by wikipedia for example) we have

ComplexConjugate[GA[5]]=GA[5] and ComplexConjugate[GA[i]]=GA[0]GA[i]GA[0] ,i=0,1,2,3.

whereas in Feyncalc

ComplexConjugate[GA[5]]=-GA[5] and ComplexConjugate[GA[i]]=GA[i].

Thanks.
