Read article 'B-factories yield first evidence for elusive D⁰–D̅⁰ mixing'
It is more than 50 years since researchers first observed particle–antiparticle mixing, with the discovery of a second, longer-lived neutral kaon state. This discovery pre-dated the quark model, but...

A paper entitled “Measurement of Bbar0 → D(*)0Kbar(*)0 Branching Fractions” became the focus of celebrations in early April, as it became the 200th to be submitted for publ...
Read article 'BaBar collaboration detects new resonance'
Charmonium spectroscopy has seen a revival over the past year or so, with various groups reporting heavy charmonium states (see CERN Courier January 2004 p9). The BaBar collaboration has now added to ...
Read article 'BaBar finds direct CP violation in B decays'
It is a classic example of the question to ask aliens from a distant galaxy to discover if they are made from what we on Earth define as matter or antimatter. Tell them to make neutral B mesons and an...

The High Energy Accelerator Research Organization has found a new and unusual particle.
Read article 'BaBar’s new particle shows unexpected traits'
The BaBar experiment at SLAC has revealed a new narrow particle state that has been identified as a charmed meson, that is, a charm quark, c, bound with an antiquark, in this case a strange antiquark,...
