A problem in understanding the Lfermion part in feynrules
Hello Madgraph team,
i am trying to learn the implementation of a new models in madgraph via feynrules.
for that i started with the SM.nb given in feynrules package.
when we see L fermion it gives me something like follows:
I phi2 Subscript[CKM, n$2287, m$2287] Subscript[
\!\(\*Overscrip
i$2287]
\!\(\*Subscript
Superscript[y,d], m$2287] - I SuperDagger[phi2]
\!\(\*Subsupers
m$2288\), \("*"\)]\) Subscript[
\!\(\*Overscrip
i$2288]
\!\(\*Subscript
Superscript[y,d], m$2288] - ((H + I phi + v) Subscript[
\!\(\*Overscrip
i$2287]
\!\(\*Subscript
Superscript[y,d], n$2287])/Sqrt[2] - ((H - I phi + v) Subscript[
\!\(\*Overscrip
i$2288]
\!\(\*Subscript
Superscript[y,d], n$2288])/Sqrt[2] - ((H + I phi + v) Subscript[
\!\(\*Overscrip
r$2287, n$2287] Subscript[
\!\(\*Subscript
Superscript[y,l], n$2287])/Sqrt[2] + I phi2 Subscript[
\!\(\*Overscrip
r$2287, n$2287] Subscript[
\!\(\*Subscript
Superscript[y,l], n$2287] - ((H - I phi + v) Subscript[
\!\(\*Overscrip
r$2294, n$2288] Subscript[
\!\(\*Subscript
Superscript[y,l], n$2288])/Sqrt[2] - I SuperDagger[phi2] Subscript[
\!\(\*Overscrip
r$2296, n$2288] Subscript[
\!\(\*Subscript
Superscript[y,l], n$2288] + I SuperDagger[phi2]
\!\(\*Subsupers
n$2287\), \("*"\)]\) Subscript[
\!\(\*Overscrip
i$2287]
\!\(\*Subscript
Superscript[y,u], m$2287] -
I phi2 Subscript[CKM, m$2288, n$2288] Subscript[
\!\(\*Overscrip
i$2288]
\!\(\*Subscript
Superscript[y,u], m$2288] - ((H - I phi + v) Subscript[
\!\(\*Overscrip
i$2287]
\!\(\*Subscript
Superscript[y,u], n$2287])/Sqrt[2] - ((H + I phi + v) Subscript[
\!\(\*Overscrip
i$2288]
\!\(\*Subscript
Superscript[y,u], n$2288])/Sqrt[2]
i wanted to what are these numbers m$2288 r$2298 etc etc here
after searching i guess its cellular aumation number .
but whats the use of this number ?
thanks !
cheers
