Has new physics been found at the ageing Tevatron?
By Anil Ananthaswamy NEVER mind the Large Hadron Collider at CERN, its ageing predecessor may have discovered a new and unexpected kind of particle. The announcement last week from the Tevatron particle accelerator at Fermilab in Batavia, Illinois, provided some excitement amid the frustration of ongoing repairs to the LHC. The Tevatron smashes protons and anti-protons together at high speed inside a 1.5-centimetre-wide “beam pipe”. Particles created by the collision are tracked by surrounding layers of electronics, whose output is then examined by researchers working on the Collider Detector at Fermilab project. In this instance,
