The user is attempting to implement the Yukawa Lagrangian for a new charged Higgs scalar, X, using the Feynrules package in Mathematica but is encountering issues with generating vertices. The Lagrangian includes terms involving the CKM matrix and quark fields defined by spin, generation, and color indices. Despite defining parameters like Y3 and Y4 as external or internal, the WriteUFO[LX] command returns no vertices. The user seeks assistance in identifying the problem with their implementation. Clarification or rewording of the post may help in eliciting responses.

Hi all,

I wonder if anyone here is familiar with Feynrules package to implement new model by Mathematica.
Actually I'm a new user for and try to implement Yukawa Lagrangian for new charged Higgs scalar called X and the charge conjugate Xbar with the SM fermions, I wrote the Lag. as :

LX := X ( - ProjP[s1, s2] (( 3 CKM[i, j] Md[j] + Ml IndexDelta[i, j] )/4 vev) tB + ProjM[s1, s2] CKM[i, j] ( Y4 cB - Y3 sB))
uqbar[s1,i,cc].dq[s2,j,cc] + Xbar ( - ProjM[s1, s2] (( 3 Md CKM[i, j] + Ml IndexDelta[i, j] )/4 vev) tB + ProjP[s1, s2] CKM[i, j] ( Y4 cB - Y3 sB)) dqbar[s1,i,cc].uq[s2,j,cc] ;

This is typically as the attached figure..

I took into account to define the quark fields by three indices : spin, generation, color, also all the Lag. parameters like Y4 and Y3 defined as External or Internal parameters . But when I run WriteUFO[LX], it gave me no vertices, so what's wrong here ..

Bests,
S.
