Searching for periodic signals in kinematic distributions using continuous wavelet transforms

Understand

Many models of physics beyond the Standard Model include towers of particles whose masses follow an approximately periodic pattern with little spacing between them.

• These resonances might be too weak to detect individually, but could be discovered as a group by looking for periodic signals in kinematic distributions.
• The continuous wavelet transform, which indicates how much a given frequency is present in a signal at a given time, is an ideal tool for this.
• In this paper, we present a series of methods through which continuous wavelet transforms can be used to discover periodic signals in kinematic distributions.
