New Physics Contributions to the Muon Anomalous Magnetic Moment: A Numerical Code

Understand

We consider the contributions of individual new particles to the anomalous magnetic moment of the muon, utilizing the generic framework of simplified models.

• We also present analytic results for all possible one-loop contributions, allowing easy application of these results for more complete models which predict more than one particle capable of correcting the muon magnetic moment.
• Additionally, we provide a Mathematica code to allow the reader straightforwardly compute any 1-loop contribution.
• Furthermore, we derive bounds on each new particle considered, assuming either the absence of other significant contributions to $a_\mu$ or that the anomaly has been resolved by some other mechanism.
