     11        Many BSM models predict the existence of a parter of the Z with enhanced (suppressed) couplings to  heavy  (light) fermions.
     12This might entail a strong suppression of the production rates, as for the Higgs. We explore the idea that, as for the Higgs, the
     13gluon gluon channel might actually provide the leading production channel.

     15=== Working plan ===
     16
     17  Phase I
     18
     19   * Verify (or not) Bij and Glover calculation  ([attachment:NPBnigel.pdf paper]). This can be done by explicit
     20      comparison or by checking the decay results.
     21   * Study the heavy top limit of the calculation and build the corresponding EFT.
     22   * Implement the EFT in Feynrules.
     23   * Perform the calculation directly in the EFT and check the results.
     24
     25  Phase II
     26
     27   * Write a code (Mathematica or Fortran or C++) which calculates cross section at hadron colliders.
     28   * Study the NNNLO effects on the Z and Z' inclusive cross section (Fabio has a code for NNLO Z production).
     29   * Implement the effective field theory in MadGraph and the full calculation correction.
     30
     31  Phase III
     32 
     33   * Get to know the models which predict a fermiophobic Z' in detail.
     34   * Construct a reasonable parameter space to be studied, including indirect constraints.
     35   * Propose discovery channels at the LHC.
     36
     37  Phase IV
     38 
     39   * Write the report and paper
     40
     41  Phase V
     42
     43   *  Book the flight to Stocholm
     44
     45
     46=== Status and reports ===
     47
     48
     49   * Here information on the status of the project is collected.
