\(\nu\)Oscillation: a software package for computation and simulation of neutrino oscillation and detection

The design of neutrino experiments and the analysis of neutrino data rely on precise computations of neutrino oscillations and scattering processes in general. Motivated by this, we developed a unified software package that calculates the expected number and energy spectrum of neutrino events in the liquid scintillation detector taking into account the neutrino flux at production, the oscillations of neutrinos during propagation and their interactions in the detectors. We also implemented the calculation of neutrino flux from nuclear reactors, the Sun, and radioactive isotopes to explorer various experimental setups using a single package. This software package is validated by reproducing the result of calculations and observations in other publications. We also demonstrate the feasibility of this package by calculating the sensitivity of a liquid scintillation detector, currently in planning, to the sterile neutrinos. This work is expected to be utilized to identify the physics potential and optimize the design of future neutrino experiments.
