Researchers at the Hungarian Academy of Sciences have revealed results that could show it in action. They saw an excited, decaying helium atom emit light when the particles split in a strange way that could not be explained by the current understanding of physics. It was the second time lead scientist Attila Krasznahorkay and his team had seen the new particle they called X17. They found its mass to be 17 megaelectronvolts.
