FEYN CALC SYMBOL

ComplexConjugate


complex conjugates expr. It operates on fermion lines, i.e., products of Spinor[..] .DiracMatrix[..] . Spinor[..], and changes all occuring LorentzIndex[mu] into LorentzIndex[ComplexIndex[mu]]. For taking the spin sum (i.e. constructing the traces) use FermionSpinSum. WARNING: In expr should be NO explicit I's in denominators!
