Two major new experiments have provided the first strong indications of the delicate CP violation effect in a totally new domain - the decays of B mesons (containing the fifth or "b" quark).
New results from the "B factories" could help to explain why a universe made of matter emerged from a Big Bang that created equal amounts of matter and antimatter.
A recent meeting in Cracow gave an overview of developments in B physics.
The DESY laboratory in Hamburg has accepted a proposal from the HERA-B experiment for a revised programme of research.
Last year the annual DESY Theory Workshop focused on rare physics - the physics that's hardest to do and sometimes difficult to understand. Andrzej Buras reports.
The world's largest data sample of J/psi particles produced directly from electron-positron annihilation has been accumulated with the BESII spectrometer at the BEPC collider in Beijing.
The year 2000 sees the debut of a new kind of precision physics. It formally began with the opening plenary talks at the International Conference on High Energy Physics, the biennial particle physic...
A neutrino experiment at Fermilab has seen the first direct evidence for the tau neutrino, the most elusive of the 12 particles that make up the Standard Model picture of the fundamental structure o...
Announced at the recent Neutrino 2000 meeting in Sudbury, Canada, were the first results from the K2K long-distance neutrino beam experiment in Japan. For the first time, synthetic neutrinos made in...
The latest precision measurement of CP violation, matter-antimatter asymmetry, by the big NA48 experiment at CERN are explored in this article from 2000.
