iMee=i(e2(p1+p1)μ(p2+p2)μ(p2p2)2e2(p1+p2)μ(p2+p1)μ(p1p2)2)


Mee=e2(P1P2+P1P2+P1P2+P1P2(P2P2)2P1P2+P2P1+P2P2+P1P1(P1P2)2)


Using the fact that \mathbf P_1^{'*} \mathbf P_2^{'*}=\mathbf P_1^* \mathbf P_2^* \quad & \quad \mathbf P_1^{'*} \mathbf P_1^{*}=\mathbf P_2^{'*} \mathbf P_2^* \quad & \quad \mathbf P_1^{*}   \mathbf P_2^{'*}=\mathbf P_2^* \mathbf P_1^{'*}


Mee=e2(2P1P2+2P1P2(P2P2)22P1P2+2P1P1(P1P2)2)


Mee=e2((P212P1P2+P22)(P21+2P1P2+P22)t(P212P1P1+P21)(P21+2P1P2+P22)u)


Mee=e2(ust+tsu)
