MSSMnuRcharges: Anomaly-Free U(1) Charge Assignments for the Supersymmetric Standard Model

130GB of compressed data lists anomaly-free charge assignments for the chiral fermionic content of the Minimally Supersymmetric Standard Model plus three right-handed neutrinos. The dataset, produced by B. C. Allanach of the University of Cambridge, includes solutions up to a maximum charge magnitude of Qmax=10. It is accompanied by C++ source code for generating the solutions, Mathematica notebooks for analytic parametrization, and filter programs for subset selection.

Use Cases

• Testing new supersymmetric models for anomaly cancellation based on the provided charge assignments.
• Parametrizing analytic solutions for anomaly-free conditions using the included Mathematica notebooks.
• Filtering the large solution space for specific phenomenological constraints using the provided filter programs.
• Benchmarking computational methods for generating charge assignments in beyond-Standard-Model physics.

Strengths

• Includes a full solution set up to a maximum charge magnitude of Qmax=10.
• Provides a smaller, more manageable subset of solutions for Qmax=4.
• Comes with reproducible generation code in C++ and analytic checks in Mathematica.

Limitations

• The primary data file is approximately 130GB when unzipped, requiring significant storage.
• Column-level documentation is absent; field semantics must be inferred from the accompanying paper.
• Row count is unknown, which may limit suitability assessment for specific computational tasks.
