What is MonopoleSFF(m1,m2,m3) in Wilson coefficients

[User001]

Dear Florian,

What is the definition of MonopoleXYZ(mloop1^2,mloop2^2,mloop3^2), with XYZ={S,F,V}?
(Picture attached)

They appear in FlavorKit WC of 1-loop penguin FFV with massLESS V.

Massless gauge bosons are treated differently using a special loop functions, as explained in FlavorKit manual 1405.1434, such as C2C12C22() in what I got.

I noticed that PreSARAH_package.m contains MonopoleXYZ(), but without the expressions.

Many thanks.

Best regards
Peiwen

Hi,

these are special loop functions for the monopole contributions. I must admit that I'm not sure, if they are written up somewhere in TeX, but you can take a look at

Code: Select all

Package/SPheno/IncludeSPheno/IncludeLowEnergy.f90

to see the Fortran expressions.

Cheers,
Florian

Dear Florian,

There is no search result of "mono" in IncludeLowEnergy.f90, but only special C functions.

In fact, in the whole folder/sub-folder of SARAH-4.13.0, I didn't find any definition of "mono" through:

grep -ir "mono" *

Could you please have a look at it? Thank you.

Best regards
Peiwen

Sorry, yes. That was moved some time ago into SPheno. Check out

Code: Select all

SPheon-4.0.X/src/LoopFunctions.f90

Dear Florian,

Many thanks. I've found it.

Best regards
