Anomaly-Free U(1) Charge Assignments for Standard Model Fermions

Lists of anomaly-free charge combinations enumerate possible U(1) symmetry assignments for Standard Model fermions, with separate files for models with and without right-handed neutrinos. The dataset includes C++ source code to generate the solutions and apply custom filters, based on a 2018 arXiv paper. This computational output supports theoretical exploration of flavour-dependent extensions to the Standard Model of particle physics.

Use Cases

• Model building based on anomaly-free U(1) charge assignments for Standard Model fermions.
• Filtering charge solutions based on custom criteria using the provided example C++ program.
• Generating new solution lists up to a specified maximum charge magnitude using the included source code.
• Comparing theoretical constraints between the Standard Model and its extension with three right-handed neutrinos.

Strengths

• Includes the complete source code used to generate the data, enabling reproducibility and extension.
• Provides separate, clearly labeled data for two distinct theoretical frameworks: the Standard Model and the Standard Model with right-handed neutrinos.
• Data is directly linked to a peer-reviewed arXiv paper (arXiv:1812.04602), providing academic context.

Limitations

• Critical metadata such as row count, file size, and specific column names are not provided on any platform.
• The last update date is unknown, making it difficult to assess the dataset's currency.
• Documentation is limited to the brief platform descriptions; no detailed data dictionary or schema is available.
