    2729=== Extra exercises 1: On-line process generation ===
    2830   * Use the on-line website to generate a few processes (with different QED + QCD couplings) trying to guess which diagrams appear:
    29       * uu~>tt~
    30       * gg>tt~
    31       * gg>tt~h (in SM and HEFT)
    32       * uu~>tt~bb~
     31      * uu~>tt~
     32      * gg>tt~
     33      * gg>tt~h (in SM and HEFT)
     34      * uu~>tt~bb~
    3335   * Subprocess identification. List all subprocesses contributing to:
    34       * pp>l+vljj
    35       * pp>tt~bb~
    36       * pp>tt~jj
     36      * pp>l+vljj
     37      * pp>tt~bb~
     38      * pp>tt~jj
    3739   * Look at the new physics models and check the particle and interactions content.
