SpecBit, DecayBit and PrecisionBit: GAMBIT modules for computing mass spectra, particle decay rates and precision observables

Understand

We present the GAMBIT modules SpecBit, DecayBit and PrecisionBit.

• Together they provide a new framework for linking publicly available spectrum generators, decay codes and other precision observable calculations in a physically and statistically consistent manner.
• This allows users to automatically run various combinations of existing codes as if they are a single package.
• The modular design allows software packages fulfilling the same role to be exchanged freely at runtime, with the results presented in a common format that can be easily passed to downstream dark matter, collider and flavour codes.
