| | 13 | During the lectures, a supersymmetric (SUSY) QCD theory is implemented. |
| | 14 | * The gauge group is SU(3)_c (as in QCD) |
| | 15 | * The field content is given by |
| | 16 | * Three generations of up-type quarks |
| | 17 | * Three generations of up-type left-handed squarks |
| | 18 | * Three generations of up-type right-handed squarks |
| | 19 | * A gluon |
| | 20 | * A gluino |
| | 21 | * The free parameters of the theory consists in |
| | 22 | * The masses of the particles |
| | 23 | * The strong coupling constant (both gs and alpha_s) |
| | 24 | * For the Lagrangian, see the slides. |
| | 25 | |
| | 26 | The implementation has been performed in three different ways which will illustrate the different features of !FeynRules. |
| | 27 | * The good old way, using regular fields including a four-component representation for the fermions: [/attachment/wiki/SchoolKias/FeynRules/susyqcd_dirac.fr susyqcd_dirac.fr] |
| | 28 | * A better approach, using regular fields including a two-component representation for the fermions: [/attachment/wiki/SchoolKias/FeynRules/susyqcd_weyl.fr susyqcd_weyl.fr] |
| | 29 | * The best method for supersymmetric theoric, using superfields: [/attachment/wiki/SchoolKias/FeynRules/susyqcd_dirac.fr susyqcd_sf.fr] |

| | 31 | In the case you want to start from your own Weyl fermion implementation to get the superfield implementation, you will have to replace right-handed Weyl quarks and right-handed squarks by their charge-conjugate counterparts. Since this will not be performed explicitly during the lectures, you can either do it yourself or download the add-on to merge to your model file [/attachment/wiki/SchoolKias/FeynRules/addon.fr here]. |
