What is it about?

We describe a new measurement technique for probing potential interactions arising from theories beyond the Standard Model of Particle Physics. Rather than a direct frequency analysis between two experimental conditions and comparing those differences we try to analyse the side-band signals.

Why is it important?

Up to now all measurements on searches for new interaction particles have lowered their potential energy/mass. In our paper we show that our technique has the potential to further lower the actual constraints.

Perspectives

An application of our measurements set-up with some more improvements could lead to data that can be analyzed in ether way, the classical frequency analysis method as well as the side-band method and should allow for constraining the energy range of beyond Standard Model particles.
