CheckMasses Error in lanhep

Asked by MohammadMohammadidoust on 2020-12-15

hello!
when I implement a model in lanhep using CheckMasses function, sometimes this error occurs in Masses.chk file:

 Incorrect kinetic term for particle '~S'/'~S' :
(+2)*p1**2

I don't know where is the source of this error and what should I do to fix this.
if it's possible please give me an advice about this error.
thanks

Hello,
this simply means that the coefficient in front of the kinetic term for

'~S'/'~S'
is twice is large as it should be,
i.e, you are missing factor of 1/2,
which means that you need to check your model implementation and fix it.

Best
Alexander
