Data Analysis Results for: Solar Neutrino Probes of Light New Physics: Updated Limits from LUX-ZEPLIN Experiment

This dataset contains the numerical analysis results and source data files (in ASCII .txt format) associated with the research paper titled "Solar Neutrino Probes of Light New Physics: Updated Limits from LUX-ZEPLIN Experiment".

The data specifically covers the exclusion limits (90% C.L.) derived from the latest LUX-ZEPLIN (LZ) electron recoil (ER) datasets via elastic neutrino-electron scattering. The analysis results included in this repository pertain to:

• Universal light mediator models: Constraints for scalar, vector, and tensor interactions consistent with Lorentz invariance.

• Anomaly-free leptophilic U(1)′ gauge extensions: Results for models featuring new vector mediators associated with Le−Lμ, Le−Lτ, Lμ−Lτ, and Le+2Lμ+2Lτ symmetries.

Data Format: The provided files are in plain text (ASCII .txt) format. Each file represents the 90% Confidence Level (C.L.) upper limit curve for a specific model. The data is organized in columns:

• Column 1: Mediator Mass (mϕ, mZ′, or mT) in MeV.

• Column 2: Coupling Constant (gϕ, gZ′, or gT).

Software & Visualization: To ensure reproducibility, this repository includes an interactive Jupyter Notebook(plot_limits.ipynb) used to generate the exclusion limit plots presented in the manuscript.

• File: plot_limits.ipynb

• Function: Automatically reads the provided .txt data files (upper_limits_90CL_...) and generates high-quality PDF plots comparing the results from the 2022 and 2024 LZ datasets.

• Requirements: Python 3, Jupyter Notebook (or JupyterLab), matplotlib, numpy.

• Usage: Simply place the notebook in the same directory as the data files, open it, and run all cells.
