mssm multiparticles
Hi,
I noticed something strange with the multiparticle definition in the mssm.
As a trivial example, suppose I generate stop decay in a simplified model containing only t1 t1~ and n1
import model mssm
define heavy = go ul cl ur cr t2 dl sl b1 dr sr b2 ul~ cl~ ur~ cr~ t2~ dl~ sl~ b1~ dr~ sr~ b2~ sve svm svt el- mul- ta1- er- mur- ta2- h+ h2 h3 sve~ svm~ svt~ el+ mul+ ta1+ er+ mur+ ta2+ h- n2 n3 n4 x1+ x2+ x1- x2-
generate t1 > n1 b w+ /heavy
The output I get on the terminal says:
INFO: Trying process: t1 > n1 b w+ / go ul cl ur cr t2 dl sl b1 dr sr b2 ul cl ur cr t2 dl sl b1 dr sr b2 sve svm svt el- mul- ta1- er- mur- ta2- h+ h2 h3 sve svm svt el- mul- ta1- er- mur- ta2- h+ n2 n3 n4 x1+ x2+ x1+ x2+
INFO: Process has 1 diagrams
1 processes with 1 diagrams generated in 0.003 s
Total: 1 processes with 1 diagrams
If you look at the particle list after the / you see that the charges of some particles are reversed (e.g. the charginos are only positive and the sleptons negative). Everything else works fine and it's probably OK but I though of pointing it out in case it leads to problems in more complicated processes.
Cheers
Gabriele
