An interactive version of the above event display can be found on this page. For more than a decade, particle-flow reconstruction has been at the core of CMS event interpretation. It was instrumental in the discovery of the Higgs…
Read moreEvery aspect of our world – from atomic nuclei and molecular chemistry to biology and astrophysics – emerges from the interactions of particles so small they are considered point-like. While some particles, like the electron, were discovered over a…
Read moreAfter an eight-week journey, the first HGCAL absorber structure (CE-H1) was delivered to CERN and is ready to be assembled, just 100 metres above the location where the detector will eventually be installed. Seventeen enormous boxes were delivered…
Read moreSpin-polarised probes have been central to nuclear and particle physics since the discovery of parity violation by Chien-Shiung Wu in 1956, who detected asymmetric emission of β-radiation from low-temperature 60Co in a magnetic field. The…
Read moreThe NA62 experiment at CERN has achieved a major milestone in flavour physics with the first observation of one of the rarest particle decays ever measured. The process — the decay of a positively charged kaon into a pion and a neutrino–antineutrino…
Read moreROOT is a software framework at the heart of HEP’s Software Ecosystem. It is an open source project, hosted on GitHub. Laboratories such as GSI, FNAL, CERN, as well as several universities contribute to it. Moreover, many talented and motivated…
Read moreLight nuclei such as the deuteron are surprisingly fragile. A deuteron is bound by only a few mega-electronvolts, yet at the Large Hadron Collider it is produced in environments that are tens of trillions of degrees – about 100,000 times hotter than…
Read moreFrom 26 to 30 January 2026, the Max Planck Institute for Physics in Garching, near Munich, hosted the 9th FCC Physics Workshop, a major gathering of theorists and experimentalists advancing the physics case, solving the experimental challenges, and…
