Hi Florian, I'm now in the same case, i.e., generating 2d2L process, is it possible that Observable_PengV2d2L.pdf file contains only one diagram ? in that case if "PSOddllVLL" is in observables, it's value will be for some specified diagram , I don't know if this 'd be some sort of "filter" can be m...

Oh sorry I deleted the old post and made another one. SARAH generates all possible diagrams brute-force. It doesn't check which vanish So that means we can get in SM a Wilson coeff. for an operator like: OddllVRR which equals (l \gamma_\mu P_R l ) (d \gamma_\mu P_R d ) , although there is no couplin...

Hi Florian, When I'm generating Observable_PengV2d2L.pdf in SARAH/Output/SM/EWSB/TeX/FlavorKit/Peng2d2l, i can't find the photon contribution, while i find only the Z boson which couples to l\bar{l} .. Also I found Wilson Coeff PVOddllVRR, PVOddllVRL, and PVOddllVLR, shouldn't they vanish in SM ? si...

Hi Florian, I try to generate 2d2L process in SM. At Folder : SARAH-4.9.3/Output/SM/EWSB/TeX/FlavorKit$ , I can find all the diagrams contributing to this process, consider for instance PengV2d2L .. in the generated pdf file i find many Feynman diagrams, for each one there is say " PSOddllVLL " , is...

Hi,

Yes, that is , many thanks ..

Hi,

Yes , I can implement a new model to SARAH, but I was just making sure that the SMLR model SU(3)xSU(2)LxSU(2)RxU(1) , isn't already in SARAH's models .

Best..

Hi Florian, I'm studying a Left right model SU_C(3)xSU_L(2)xSU_R(2)xU_{B-L}(1) , I searched in SARAH for LR models, where i found 4 models: i think the nearest model for mine is LRLR : which is SU_C(3)xSU_L(2)xSU_R(2)xU_{L}(1)xU_{R}(1) .. i mean should i add the version of LRSM to the LR models in S...

Hi Florian,

Thanks for your reply. I run SSP on the MathKernel and I knew what was the error.

Dear sir, I try to use SSP by running Example1.m which makes scan on M0 in MSSM as the attached file, but after i type Start["Example1.m"] it gives: Starting parameter scan ScanM0 total number of parameter points: 10 20.% done 30.% done 40.% done 50.% done 60.% done 70.% done 80.% done 90.% done 100...

Hi sir,

I try to calculate the MSSM Wilson coefficients of b->c \tau\nu on the loop level , On the tree level we can type:

Vertex[{bar[Fu], Fd, conj[VWm]}]
Vertex[{bar[Fe], Fv, VWm}]

Any help about what can I use on the loop level ?

Best.
