Example.main(parameterFile, outputFile, showPlot=True)

Main code to define the BSM contents and properties and solve the Boltzmann equations

Parameters:

• parameterFile – Path to the file defining the main model parameters
• outputFile – Path to the output file. If None, no results will be written.
• showPlot – If True, will show a simple plot for the evolution of the energy densities

synopsis:This module provides decay classes and methods author:Andre Lessa <lessa.a.p@gmail.com>

class AuxDecays.Decay(instate=None, fstates=None, br=0.0)

Bases: object

Main class to store information about a specific decay.

Parameters:

• motherID – ID for the decaying mother
• fstateIDs – list of IDs for the daughters
• br – branching ratio value

compress(ID, IDecays)

Generates a new DecayList() from compressing the ID decays

class AuxDecays.DecayList

Bases: object

Main class to store information about all the decays of a specific species.

Parameters:

• dlist – List of Decay objects
• width – Total width
• Xfraction – fraction of energy injected in the thermal bath
