Tevatron Data Reveals No Exotic, Non-Standard Model Higgs

She may be long gone, but the old gal still has something to say.

A new paper that combined the data from CDF and D0, the two old Tevatron detectors at Fermilab, has revealed that the Higgs that has been found is indeed consistent with the Standard Model Higgs. It strengthens the much-heralded discovery made at CERN a while back.

...... the two Tevatron-based experiments, CDF and D0, uncovered evidence in 2012 of a Higgs boson decaying into fermions, specifically, a pair of bottom quarks. The two collaborations have again combined their data to check for exoticness in this fermion decay channel. The Tevatron data show no signal consistent with a Higgs boson having spin zero and odd parity (a so-called pseudoscalar) or spin 2 and even parity (gravitonlike). The results are important for building the case that the Higgs boson seen in particle colliders is indeed the standard model Higgs.
