Belle finds more exotic mesons
The Belle collaboration has announced the discovery at the Japanese B-factory, KEKB, of three new exotic sub-atomic particles, which they have labelled the Z1, Z2 and Yb. The Z1 and Z2 states appear t...

BaBar gets right to the bottom
The BaBar collaboration, working at SLAC has observed the ground state of the bottomonium family, the ηb meson. Bottomonium particles are bound states of a bottom quark and its antiquark. The first ...

Belle sees a difference in direct CP violation between charged and neutral B decays
The Belle collaboration, working at the KEKB facility at KEK, has observed a difference in the direct CP asymmetry for decays of charged and neutral B mesons into a kaon and a pion. This res...

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...
