Description of Research & Links:

The Belle (French word for beauty) experiment studies the properties of the ephemeral beauty (b) quark. The b quark is produced in pairs with the anti-b quark at the KEKB e⁺e^- asymmetric collider. The Belle experiment studies the decay patterns of the b-quark to search for clues on how our universe is constructed.
