oscillations

Calculate neutrino oscillation probabilities easily.

Installation

You can install oscillations from PyPI in the usual way...

pip install oscillations

Basic Example

Here's a basic example of how to use the module:

import oscillations

osc = oscillations.Oscillations()

osc.setTheta23( 90.0 * oscillations.units.degrees )
osc.setE( 1.0 * oscillations.units.GeV )
osc.setL( 3000.0 * oscillations.units.km )

p = osc.p(oscillations.nu_mu, oscillations.nu_e)
print("P(nu_mu -> nu_e) = ", p)

print("Parameters used:")
print(osc)

Remember to always use the oscillations.units constants to convert to the correct units whenever you call the set parameter methods of Oscillations.

Preset Parameter Examples

For convenience, there are three functions which return Oscillations objects with the parameters set according to values from recent PDG summary tables.

osc_2013 = oscillations.pdg2013()
osc_2020 = oscillations.pdg2020()
osc_2022 = oscillations.pdg2022()

More Examples

There are multiple examples of the use of the module in plots.py, which includes the code used to generate all the oscillations plots in my PhD thesis.

To run plots.py, you will need to have PyROOT installed and loaded.

Physics

The module uses the standard PMNS matrix calculation for neutrino oscillations in a vacuum.

Neither matter effects nor sterile neutrinos are currently included.

Unit Tests

Some basic unit testing is conducted in test.py, which uses Python's unittest module (PyUnit).
