Work Assignement

The exercise is to explain the Forward-Backward asymmetry at the Tevatron with an extension of the SM. It can be one of the following example :

  1. an axigluon (see for example 1103.0956)
  2. a t-channel flavor mixing new particle (see for example 0907.4112)
  3. an effective theory (see for example 1010.6304)
  4. or your favorite model.

The model should be implemented in FeynRules and then used in MadGraph5_aMC@NLO to obtain the parameters constraints from the measured value of the asymmetry but also to see what are the other signatures of the model at the LHC and the Tevatron. Eventually, the model can be further constrained. The SM contribution should be computed at NLO with the parton shower. The BSM contribution can on the other hand be only computed at LO but with matching/merging. If you do not have an access to mathematica, you can do the phenomenological analysis using this model.

The report should be send by email (see above) to the lecturers before January 2015. In attachment of your report, it is asked that you provide the FeynRules model file and the banner file of each generation.
