data module

Module to load and process antiproton data.

Contains class for AMS-02 7-year antiproton data. Module can be easily extended with additional classes for new datasets.

pbarlike.data.R_to_Ekin(R, z=-1, A=1, m=0.9382720881604903): Converts R in GV to kinetic energy per nucleon in GeV,

\[E_k / A = \sqrt{(RZ/A)^2 + m^2}\]

class pbarlike.data.ams02Data(include_low_energy=False)

Bases: object

Class to load and process AMS-02 7-year dataset.

Note

Always add new classes with same attributes for compatibility with rest of the code.
Measurements below \(10 \ GeV\) are neglected by default, due to uncertainties induced by approximate modeling of solar modulation.
AMS-02 data correlations have not been made public by the AMS collaboration. The data correlations included here were modeled in [5].

pbar_flux

Antiproton flux values in \((m^2 \ sr \ s \ GeV)^{-1}\)

energy

\(GeV\) energies at which antiproton flux values are measured.

errors

Uncorrelated data errors.

correlations

Data correlations.

Parameters:: include_low_energy (bool) – Whether or not to include low energy region affected by solar modulation; default - False.

pbarlike.data.flux_in_Ekin(flux_in_R, R, z=-1, A=1, m=0.9382720881604903): Converting flux \((m^2 \ sr \ s \ GV)^{-1}\) in R to flux \((m^2 \ sr \ s \ GeV)^{-1}\) in E,

\[\frac{d \phi}{d R} \frac{d R}{d (E_k/A)} = \frac{d \phi}{d R} \frac{1}{R} (\frac{A}{Z})^2 \sqrt{( \frac{RA}{Z})^2 + m^2}\]
