The pixel tracker is the subdetector that is closest to the beamline in the CMS experiment. Credit: CERN After more than two years of maintenance and upgrades, the Pixel Tracker has been installed at the center of the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC) and […]

A train of short proton bunches travels through the plasma field, forming a wave on which electrons can be accelerated. Credit: AWAKE Important milestone for next-generation acceleration experiment. The future of particle acceleration has begun. Awake is a promising concept for a completely new method with which particles can be […]

Trapped anti-atoms being cooled. Credit: Chukman So The result opens the door to considerably more precise studies of the response of antimatter to light and of how it behaves under the influence of gravity. Swansea University physicists, as leading members of the ALPHA collaboration at CERN, have demonstrated laser cooling of […]

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, […]

Using collision data from the ALICE detector at the Large Hadron Collider at CERN, the strong interaction between a proton (right) and the rarest of the hyperons, the omega hyperon (left), which contains three strange quarks, was successful measured with high precision.

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 […]

An artist’s impression of the new tetraquark showing the individual constituent particles. Credit: Daniel Dominguez/CERN) The particle, which has been called X(2900), was detected by analyzing all the data LHCb has recorded so far from collisions at CERN’s Large Hadron Collider. The LHCb experiment at CERN has developed a penchant for […]

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 […]

Simulation of the dark-matter distribution in the universe. Credit: V. Springel et al. 2005 The latest on the Large Hadron Collider’s hunt for the hypothetical particle that may make up dark matter. The Large Hadron Collider (LHC) is renowned for the hunt for and discovery of the Higgs boson, but […]
