Detailed Description

Flat transfer function on Theta (mainly for testing purposes).

This modules implements a constant (=1) transfer function on a particle's \(\theta\).

The primary purpose of this module is the validation of the phase-space generator, since it allows computing phase-space volumes and cross-sections by integrating over the reconstructed particle's momenta.

The module still takes a 4-momentum as input, since it needs an energy, a \(\phi\)-angle and a mass.

The range of \(\theta\) values considered is \([0,\pi]\).

Integration dimension

This module requires 1 phase-space point.

Inputs

Name	Type	Description
`ps_point`	double	Phase-space point generated by CUBA.
`reco_particle`	LorentzVector	Input LorentzVector (experimentally reconstructed particle).

Outputs

Name	Type	Description
`output`	LorentzVector	Output generated LorentzVector, only differing from reco_particle by its \(\theta\).
`TF_times_jacobian`	double	Transfer function (ie, 1) times the jacobian (due to the integration range).
