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.
