Generated diagrams - all of them ?

Asked by Maria Giulia Ratti

Dear experts,
I am generating a process in mssm using the instructions as below (the complete proc_card is pasted at the end).

define susylq = ul ur dl dr cl cr sl sr
define susylq~ = ul~ ur~ dl~ dr~ cl~ cr~ sl~ sr~
define p = g u c d s u~ c~ d~ s~
define j = g u c d s u~ c~ d~ s~

generate p p > susylq susylq~ $ go susyweak @1
add process p p > susylq susylq~ j $ go susyweak @2
add process p p > susylq susylq~ j j $ go susyweak @3

I would expect to obtain diagrams with second generation squarks in the intermediate state as well as first gen. squarks.
However among the output diagrams in MG, I see only first gen. squarks in the intermediate state.

Do you think it is possible that these diagrams get omitted because there are identical diagrams for first gen. squarks ?

Thanks very much,
Maria-Giulia

Hi,

Did you look at the HTML/info.html page.
There you have the link to the Feynman diagram and the list of processes wich have the exact same Feynam diagram.

Cheers,

Olivier

Thanks Olivier Mattelaer, that solved my question.

Hi,
thanks they appear there. I could't find them immediately just based on the naming of the processes that appear in the /HTML/Run-test/results.html page. But if I click on each process, all different contributions are visible.

Cheers,
Maria Giulia
