Interface

Flavour Les Houches Accord NEW

The objective of this accord is a clear and well-defined structure for interfacing computational tools of "New Physics" models with low-energy flavour calculations. More information...

Tools

We do not attempt to provide yet another database with tools. We simply put a list of existing tools. Most of them are available here.
Note: only flavor observable related tools are listed here.

If you want to add something to this list, send an email to Sven.Heinemeyer@cernNOSPAMPLEASE.ch .

General questions that should be answered:

  • What is still missing? Are all relevant topics covered?
  • How can it be ensured that a code/calculation is useful/usable for others?
  • Can experimentalists make use of them?
  • What are the wishes of the experimentalists?
  • Interaction between theory and experiment?



Benchmarks

Benchmarks can be used to

  • study the complementarity of low- and high-energy experiments
  • study the synergy of low- and high-energy experiments

Three different approaches have been discussed:

  1. Take the good old SPS points (some have been studied in quite detail)
    → evaluate LHC measurements
    → investigate what B physics can add
    This appoach has been used e.g. for SuperB investigations.
  2. Take a GUT based model with flavor violation
    → fit to current data
    → fit to anticipated LHC data
    → investigate what B physics can add
  3. Define benchmark scenarios (in GUT based models)
    → investigate compatibility with existing constraints
    → investigate what B physics can add (in the future)
    This approach has partially been realized in the NUHM.
