Prob3++ is software for computing three flavor neutrino oscillation probabilities based on the work of Barger et al. Phys. Rev. D22(1980) 2718. It has been written by members of the Super-Kamiokande collaboration in C/C++ and is available for public use at the links below. Example programs designed to explain the code usage as well as documentation are included. | ||||||||||||||||||||||||||||||
As of December 2018 support for Lorentz invariance-violating oscillations has been added to the library. The computation uses the SME framework (A. Kostelecky et al.) and follows the parameterization in Phys. Rev. 91 052003. |

Example output
This is the muon survival probability as a function of neutrino zenith angle and energy for theta 13 mixing (normal hierarchy) at the Chooz limit as computed by the code in the 2009.08.31 release. The Earth-matter effects are visible as distortions in the oscillation pattern, particularly at several GeV. ![]() |
Example output for Lorentz-violating oscillations
Muon survival probability as a function of neutrino zenith angle and energy for d=4 Isotropic LIV (Cmutau = 7.5e-23) with PMNS oscillations. ![]() |
Compilation
The main library can be built under any standard C++ compiler. In order to make the included example programs you will additionally need a copy of ROOT. |
