ERROR: Illegal character '['

Hi Charlie,

UFO model followed python convention and not Feynrules convention.
Therefore you have to replace
> value = 'MW2/MW*Sqrt[(k1**2+k2**2)/2]',
by
> value = 'MW2/MW*cmath.sqrt((k1**2+k2**2)/2)',

(you can also use "math." instead of "cmath." in principle)

Of course this assume that MW2, MW, k1 and k2 are already define above in the file.

Cheers,

Olivier

Hi Olivier,

Thanks for your kindly reply.

I also want to know if I do a parameter scan , How can I put the results in one file so that I could plot it, say the cross section to the mass of the particle.

Best!
Charlie
