These are couplings of my model: but I have assumed $\theta^{\mu\nu}$ as matrix as following : $\theta^{\mu\nu}$ =\begin{pmatrix} 0 & -1 & -1 & -1 \\ 1 & 0 & -1 & 1 \\ 1 & 1 & 0 & -1 \\ 1 & -1 & 1 & 0 \end{pmatrix} Would you please help me how can I...

Hi; Thank you so much in advance for any help. My question about FeynArts model file, I have coupling of my model and I did arrive to insert (write) constant 4*4matrix in generic model file in Feynarts or I should write it in model file. Thanks again
