PreSARAH-1.0.3, “Generic” appears in output, no mass/coupling substitution

[User001]

Dear Florian,

I get abnormal results when running PreSARAH-1.0.3 on my MacBook Pro, with Mathematica 10.4.1.0 installed and macOS Mojave 10.14.1

I attached my working NoteBook and Output-Gamma2Q.m in this post.

<< /Users/peiwen.wu123/Downloads/PreSARAH-1.0.3/PreSARAH.m
GetCodeForSARAH["PhotonQQp.m"];

In the output, I found that model coupling/mass substitutions defined in PreSARAH_package.m do NOT work at all. That is, I“Generic” notation appears throughout Output-Gamma2Q.m

WriteStringFLB[file," OG2qSL=OG2qSL+2.*chargefactor*(G(-1.)(0.)(F(Index(Generic, 6.), Loop), F(Index(Generic, 5.), Loop)…


Do you have an idea of what may causes this?


Actually, I am trying to get penguin WC for 1-loop Up-type quark FCNC vertices, e.g. U1-U2-V, with V=photon, Z, gluon, without ignoring m_U1, m_U2.

I have been puzzled by the above issue for a while. If possible, could you please generate the PreSARAH output of U1-U2-V for me? I attached the Input for PreSARAH in this post.

Thank you very much.

Input-U1U2Gluon.m
Input-U1U2Photon.m
Input-U1U2Z.m

Best regards
Peiwen

Here is the version of FeynArts and FormCalc I added in PreSARAH.ini

FeynArtsPackage = "/Users/peiwen.wu123/Downloads/FeynArts-3.10/FeynArts.m";
FormCalcPackage = "/Users/peiwen.wu123/Downloads/FormCalc-9.6/FormCalc.m";

That's most likely due to changes in Feynarts/FormCalc. I don't have time to dig into the new versions to see what has changed. I usually use 3.9 and 9.2. That should be still available online.

Dear Florian,

I found that everything works just fine on macOS High Sierra, Version 10.13.6.

Therefore this is another example of OS update issues.

Many thanks.
