For 50 years, the research community has been hunting unsuccessfully for the so-called Odderon particle. Now, a Swedish-Hungarian research group has discovered the mythical particle with the help of extensive analysis of experimental data from the Large Hadron Collider at CERN in Switzerland. In 1973, two French particle physicists found that, according […]

The Compact Muon Solenoid (CMS) is a general-purpose detector at the Large Hadron Collider (LHC). Credit: CERN The bounds are some of the tightest yet on the existence of third-generation leptoquarks. At the most fundamental level, matter is made up of two types of particles: leptons, such as the electron, […]

CMS candidate event for a top quark and antitop quark producing an electron, a muon and jets originating from bottom (b) quarks. Credit: CERN The result opens the path to study in a new and unique way the extreme state of matter that is thought to have existed shortly after […]

Visible matter – everything from pollen to stars and galaxies – accounts for roughly 15% of the total mass of the Universe. The remaining 85% is made of something entirely different from things we can touch and see: dark matter. Despite overwhelming evidence from the observation of gravitational effects, the […]
