Now it is more likely than ever: There must be particles out there smaller than Higgs particle. Nobody has seen them yet; particles that are smaller than the Higgs particle. However theories predict their existence, and now the most important of these theories have been critically tested. The result: The existence of the yet unseen particles is now more likely than ever. “I gave them a very critical review “, says Thomas Ryttov, particle physicist and associate professor at the Center for Cosmology and Particle Physics Phenomenology (CP ³ – Origins), University of Southern Denmark. He refers to the theories, that over the last app. five years have been put forward ​​for the existence of particles in the universe that are smaller than the Higgs particle. Having given these theories a critical review, he finds no new signs of weakness in them: “There seems to be no new or unseen weaknessess. My review just leaves them just stronger”, he says. Over the past 5-8 years, a handful of theories have drawn particular interest from particle physicists. They all predict that there must be one or more types of particles that are even smaller than the Higgs particle. So far it has however
