CERN's main objectives for 2021–2025
2023年9月5日 · This document describes the CERN Management’s vision for the period 2021 – 2025, its term of office. The objectives envisaged cover CERN’s scientific programme and other strategic activities that are crucial to the mission and future of the Organization.
Heavy ions and quark-gluon plasma - CERN
CERN physicists collide heavy ions to recreate the quark-gluon plasma that existed in the early universe. Learn how they study the properties and behaviour of this exotic state of matter using jets, a type of debris that reveals the quark-gluon plasma's effects.
The LHC lead-ion collision run starts - CERN
2023年9月28日 · The LHC is back delivering collisions to the experiments after the successful leak repair in August. But instead of protons, it is now the turn of lead ion beams to collide, marking the first heavy-ion run in 5 years. Compared to previous runs, the lead nuclei will be colliding with an increased energy of 5.36 TeV per nucleon pair (compared to 5.02 TeV previously) and the collision rate has ...
AMS Days at CERN and latest results from the AMS experiment
2015年4月15日 · The Alpha Magnetic Spectrometer (AMS) collaboration will present today the latest results in its quest to understand the origin of cosmic rays and dark matter. These intriguing results will be shared and discussed during the “AMS days” starting today at CERN with many of the world’s leading theoretical physicists and principal investigators of some of the major experiments exploring the ...

The Safety of the LHC - CERN
CERN's LHC Safety Assessment Group (LSAG) reviews the possible risks of producing strangelets, microscopic lumps of strange matter, in high-energy particle collisions. It concludes that strangelets are unlikely to form and that they would decay rapidly if they did.
Probing fundamental symmetries of nature with the Higgs boson
2023年4月21日 · Where did all the antimatter go? After the Big Bang, matter and antimatter should have been created in equal amounts. Why we live in a Universe of matter, with very little antimatter, remains a mystery. The excess of matter could be explained by the violation of charge-parity (CP) symmetry, which essentially means that certain processes that involve particles behave differently to those that ...
The LHCb experiment is charmed to announce observation of a …
2017年7月6日 · The LHCb experiment is charmed to announce observation of a new particle with two heavy quarks Geneva, 6 July 2017. Today at the EPS Conference on High Energy Physics in Venice, the LHCb experiment at CERN’s Large Hadron Collider has reported the observation of Ξcc++ (Xicc++) a new particle containing two charm quarks and one up quark.
Accelerating Science - CERN
2022年1月12日 · What is the Universe made of? Where did it come from, where is it going and why does it behave the way it does? These are some of the questions that CERN set out to address when a small number of pioneering scientists created Europe’s first scientific international organization. Founded in 1954 ...
