Evidence Mounts for New Physics via Tevatron Particle Collider

A group of physicists working with data from a particle detector at the Tevatron collider announced last month that they had found something they could not explain. High-speed smash-ups between protons and their antimatter counterparts, observed by the Illinois site’s CDF detector, appeared to yield a certain kind of package in unexpected abundance : a massive particle known as the W boson along with two jets of other particles. The CDF excess hinted at the existence of some unknown particle, an unidentified and possibly disruptive addition to the family of particles described by the long-reigning, exceptionally well-tested Standard Model of particle physics
