WallGo.collisionHelpers

Conversion between WallGo and WallGoCollision types

Functions

convertParticleStatistics(statisticsName)	Convert "Fermion" or "Boson" (string) to a type-safe enum.
dictToCollisionParameters(inParameterDict)	Convert a python dict of named float parameters to a WallGoCollision ModelParameters object.
generateCollisionModelDefinition(wallGoModel)	Automatically generates a WallGoCollision.ModelDefinition object with matching out-of-equilibrium particle content and model parameters as defined by the input dict.
generateCollisionParticle(particle, ...)	Creates a WallGoCollision.ParticleDescription object from a WallGo.Particle.

convertParticleStatistics(statisticsName)

Convert “Fermion” or “Boson” (string) to a type-safe enum. FIXME: Python has enums too. Use them instead of strings.

Parameters:

statisticsName (str)

Return type:

EParticleType

dictToCollisionParameters(inParameterDict)

Convert a python dict of named float parameters to a WallGoCollision ModelParameters object.

Parameters:

inParameterDict (dict[str, float])

Return type:

ModelParameters

generateCollisionModelDefinition(wallGoModel, parametersForCollisions={})

Automatically generates a WallGoCollision.ModelDefinition object with matching out-of-equilibrium particle content and model parameters as defined by the input dict. You will need to manually add any relevant in-equilibrium particles. Currently this function defines all collision particles as ultrarelativistic.

Parameters:

• wallGoModel (WallGo.GenericModel)

• model. (WallGo physics model to use as a base for the collision)

• defs. (We take the model's outOfEquilibriumParticles list and create corresponding collision particle)

• parametersForCollisions (doct[str, float])

• symbols (Dict of)

• values. (and their current)

Returns:

A partically filled collision model definition that contains all out-of-eq particles from the input model and has its model parameter list filled with (symbol, value) pairs as specified by the input dict.

Return type:

WallGoCollision.ModelDefinition

generateCollisionParticle(particle, inEquilibrium, ultrarelativistic)

Creates a WallGoCollision.ParticleDescription object from a WallGo.Particle. Note that currently this function does not support non-ultrarelativistic particles (ultrarelativistic=True raises an error).

Parameters:

• particle (Particle)

• inEquilibrium (bool)

• ultrarelativistic (bool)

Return type:

ParticleDescription
