We are thrilled to host the 2025 European Physical Society Conference on High Energy Physics in the vibrant city of Marseille, France. This exciting event will take place at the iconic Palais du Pharo ...

LHC physics Effective field theory enables a deeper understanding of complex physics processes at the LHC, such as the above production of Higgs bosons in ATLAS. Credit: ATLAS-CONF-2022-032.

In a 2021 analysis of the same B + → J/ ψφ K + decay mode including LHC Run 2 data, LHCb reported two more neutral states, χ c1 (4685) and X(4630), that do not correspond to cc states expected from ...

Testing CP symmetry. The three neutrino mass eigenstates mix to make electron, muon and tau neutrinos according to the Pontecorvo– Maki–Nakagawa–Sakata (PMNS) matrix, which describes three rotations ...

With just 5% of its ultimate dataset collected so far, the LHC’s vast and unique physics programme has already transformed and enriched our understanding of elementary particles, writes Michelangelo ...

In the summer of 1968, while a visitor in CERN’s theory division, Gabriele Veneziano wrote a paper titled “Construction of a crossing-symmetric, Regge behaved amplitude for linearly-rising ...
