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 ...

Threading the needle The LHCb experiment at CERN sparked a renaissance in charm physics with two intriguing measurements that challenge theorists to improve the precision of their predictions. Credit: ...

Accelerating into the future Seventy years after construction began on CERN’s still-operational Proton Synchrotron (above, left), a new generation of researchers is being called upon to help conceive ...

The past seven decades have seen remarkable cultural and technological changes. And CERN has been no passive observer. From modelling European cooperation in the aftermath of World War II to ...

Misfits Massive neutrinos are not part of the Standard Model. Credit: Symmetry After all these years, neutrinos remain extraordinary – and somewhat deceptive. The experimental success of the ...

After 25 years of steady progress, recent advances in theory and computing are enabling researchers to connect an approach to quantum gravity called asymptotic safety to the Standard Model. Frank ...

Looking ahead, the next milestone for the HL-LHC crab cavity programme is the testing of the first RFD module in the SPS. Currently, this module is being assembled at Daresbury Laboratory and will be ...
