Interface

Flavour Les Houches Accord

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.

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.
