Searching for Tensor Currents by Detection of Cyclotron Radiation

Chirality plays a fundamental role in the Standard Model, where the charged weak current is modeled as purely left handed. Models for new physics naturally break this symmetry so sensitive searches for chirality-flipping interactions could be a powerful tool for discovery.

We will discuss a sensitive search for chirality-flipping interactions by measuring the shape of the beta spectrum of 6He. We are building a prototype to make a proof of principle for using the technique of cyclotron radiation emission spectroscopy (CRES), recently demonstrated for low-energy electrons, by the Project 8 collaboration.
