Positron spectra¶
Overview¶
In order to compute the limits on a given model from energy injections
into the CMB spectra, one needs to know the gamma-ray and electron/positron
spectra for the model. hazma contains a dedicated module,
positron_spectra, for computing the electron/positron spectra from
decays of \(\pi^{\pm}\) and \(\mu^{\pm}\). As in the decay
module, the positron_spectra module allows users to compute the
electron/positron spectra for arbitrary energies of the parent-particle.
The procedure for computing the spectra for arbitrary parent-particle
energies is identical to the procedure used for decay. In addition
to the decay spectra of muons and pions, hazma contains a function to
compute the electron/positron from a matrix element called positron_decay.
