From Quantum Scoop: The Holy Grail of particle physics may already have been found which was linked on Slashdot yesterday.
The current rumor, which comes in time for the summer conference circuit, may be different. It claims an experiment at the Tevatron has found a peak twice as high as the previous rumors’ bumps. And unlike the other rumors, this one includes details: the new particle’s mass, for instance, which fits within theoretical bounds on the standard model Higgs. Some versions include a decay chain, which describes what the new particle turned into as the experiment progressed, and which may be consistent with the standard model’s predictions.
