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
