# Transposed Spinors in Lagrangian

Dear colleagues,

I am greatly interested to use CalcHEP to calculate cross sections in the Nucleon Nucleon scattering. Is it possible to use CalcHEP, if the Lagrangian contains transposed spinors (\psi^T)? For example there are the following products in the terms of the Lagrangian:

$\psi^T C \gamma^\mu \psi$ or $\psi^T C \gamma^5 \psi$ and the corresponding hermitian conjugates (C is the matrix of charge conjugation).

I would be grateful if you could answer my question asap. If transposed spinors are possible with CalcHEP, it would be appreciated if you could give me instructions how to proceed.

Best wishes

Werner Deinet
