Thank you for help but i am getting the following output :
for h :-
Contract(Subscript\[CurlyEpsilon], \[Mu] Overscriptu, _.\[Gamma]^0.u(p1,m1))
for h2 :-
4 Contract(\!\(
\*SubsuperscriptBox\(\[CurlyEpsilon]\), \(TraditionalForm\`\(TraditionalForm\`\[Mu]\)\), \(*\)\) HighEnergyPhysics`fctools`DiracTrace`Private`spursav(\CurlyPhi,\[Gamma]^0,\CurlyPhi)) Contract(Subscript\[CurlyEpsilon], \[Mu] HighEnergyPhysics`fctools`DiracTrace`Private`spursav(\CurlyPhi,\[Gamma]^0,\CurlyPhi))

I don’t know about this error message .
