Four of a kind: exploring quadruple-Higgs boson production at the HL-LHC
Four Higgs bosons from a single LHC collision would be a remarkable sight. The Standard Model puts an observation out of reach at the High-Luminosity LHC. Yet events containing four Higgs bosons could still matter for today’s experimental search strategies—and become much more abundant if new scalar particles exist.

Moving antimatter beyond the lab
Moving antimatter beyond the lab For decades, antimatter experiments have been bound to a single place: the laboratory in which the particles are produced and trapped. At CERN’s Antimatter Factory, antiprotons are routinely produced, decelerated and confined in Penning traps, where electric and magnetic fields are used to store charged particles for high-precision studies. Yet

Sympathetic Cooling Opens a New Era for Antihydrogen at CERN
Sympathetic Cooling Opens a New Era for Antihydrogen at CERN A major milestone has been reached at CERN’s Antimatter Factory. Using an innovative technique to cool positrons with laser-cooled beryllium ions, the ALPHA collaboration has increased the rate of antihydrogen production by a factor of eight. The advance, reported in Nature Communications, has transformed the

Unlocking the Secrets of Antimatter: A journey through low-energy antimatter studies at CERN
Unlocking the Secrets of Antimatter: A journey through low-energy antimatter studies at CERN The existence of antimatter is a fundamental aspect of our Universe and is predicted by the laws of quantum physics and symmetry principles. However, the theory does not match the experimental observations. According to our models, we would expect to have a

New Milestones in direct CP Violation: Observation in Baryons and First Evidence in Beauty Mesons to J/Psi
New Milestones in direct CP Violation: Observation in Baryons and First Evidence in Beauty Mesons to J/Psi A Milestone in Understanding the Matter-Antimatter Asymmetry The LHCb collaboration has announced a groundbreaking achievement: the first-ever observation of CP violation in baryon decays. This result, presented at the Rencontres de Moriond EW conference and submitted for publication

CERN’s BASE-STEP: A Leap Forward in Antimatter Transport
CERN's BASE-STEP: A Leap Forward in Antimatter Transport Antimatter, often portrayed as the elusive counterpart to ordinary matter, has long captivated the scientific community with its potential to unlock some of the universe's most profound mysteries. Yet, one of the most significant challenges in studying antimatter is its inherent instability—it annihilates upon contact with matter,
