New physics theory?

Grosvenor2

I recently heard about the experiments made by Fedor Ignatov and Korbely Todyshev who just received a prize for a series of studies on the properties of elementary particles in colliding electron-positron beams.
Unfortunately I haven't been able to find out what exactely their discovery is about, as I'm new in the physics enviroment and I couldn't fully understand the specific terminology I found in some scientific articles.
Could somebody clarify it to me in a more accessible way?
