The experiment at the Tevatron particle collider has released a paper on the Arxiv
stating it has found evidence for a potential new particle that isn't
the Higgs boson. A live stream announcing the results
will begin at 4pm Central time (21:00 GMT).
Excess events (at 3.2 standard deviations) were found in quark jet events corresponding to a particle mass around 144 GeV. Dedicated Higgs searches in the same mass region turned up negative, implying that this could be non-Standard Model physics. The paper, cautiously, makes no guesses about what kind of physics is being observed.
CDF's sister experiment at the Tevatron, D0, has yet to weigh in. Whether D0 sees the same signature will go a long way in confirming whether a signal is actually present.
