Dark matter, CEνNS and neutrino new physics scrutinized by a statistical method in Xenon-based experiments

This is the codes for reproducing results from our paper arXiv:[2403.05819]. You can simply run the notebooks. Most computations can be done within 15 minutes.

We organize four files to content different materials:

• [src/] - Contains functions used in producing results
• [plots/] - Contains all the plots in pdf and png formats
• [notebooks/] - Jupyter notebooks for obtaining and plotting results
• [data/] - data files, including neutrino fluxes, experimental exclusion limits, and the MC data

All classes and functions we use to derive results in our paper are maily included in [src/]:

• [LabFuncs.py] - Various utilities (from Ciaran's code)
• [Params.py] - Some useful parameters and functions (from Ciaran's code)
• [WIMPFuncs.py] - Functions needed to calculate WIMP rates (based on Ciaran's code)
• [propagation.py] - A class to compute the neutrino propagation from the sun to the Earth
• [U1Funcs.py] - Functions needed to calculate neutrino rates w/wo new physics
• [U1PlotFuncs.py] - Plotting functions
• [StatisticFuncs.py] - Main classes and functions Here, we also provide a code diagram for better understanding:

Bases on materials above, we offer several notebooks to obstain figures in our paper:

• [Spectrum.ipynb] - Figures 1
• [DM-N.ipynb] - Figures 2 & 4
• [DM-e.ipynb] - Figure 3 & 4
• [Exclusions.ipynb] - Figure 5
• [Different DM-N.ipynb] - Figure 6
• [Different DM-e.ipynb] - Figure 6
• [MCPlot.ipynb] - Figure 7

Attention

Our work is based on the reference arXiv: 2304.13665 and the repository zhangblong AsymptoticAnalysisAndNeutrinoFog. And some codes are from Ciaran NeutrinoFog. The codes used to obtain DM-e scattering event rates are from T.T. Yu QEdark.

Requirements

• CMasher
• Numba
• labelLine
