Right, we essentially just took that as the chiral Lagrangian for the vector mesons but I didn’t check it any deeper .. I have far more in depth notes I took that I could send you
Here's a snapshot of how i dealt with the finding the feynman rules if it helps at all .. this is for the πωρ vertexpic.twitter.com/4ondZ0GEEK

i imagine this method of 'factoring' would work similarly for the ωρφ vertex .. good luck, though .. i remember that references for the vector mesons in the anti-symmetric representation took a lot of digging

Is there a good way to translate between interaction vertices expressed a) in "antisymmetric tensor representation" for vector mesons to b) their "usual" vector representation? To re-express your Feynman rule for rho_mn - omega_mn - pi to the "usual" rho_m - omega_n - pi ?

Thanks, that's the interaction term from (11) in http://arxiv.org/abs/1903.10632 apparently taken from p. 7 in http://arxiv.org/abs/1204.4125 I'd like to understand how that would relate to all the other literature I cited, as it seems to differ(?).

ah, i see your question now .. that's a really interesting point
