A 'Golden Channel' for New Physics

A group of physicists has dubbed a particular particle decay, the decay of the Bs meson into a neutral kaon and neutral antikaon, as a “golden channel” for new physics, suggesting that probing and studying the decay could lead to brand-new insight into the physics laws that govern the tiniest bits of matter. The scientists discuss their ideas, and how this decay could be studied in the future, in the January 25, 2008, edition of Physical Review Letters.
