Higgs physics at the Tevatron

TL;DR

This paper reports on the combined analysis of Tevatron data, observing a 3-sigma excess at 125 GeV/c^2 consistent with the Higgs boson, and investigates its spin-parity and fermionic properties.

Contribution

First comprehensive Tevatron analysis combining multiple channels, confirming the Higgs-like signal and exploring its quantum properties.

Findings

Approximately three standard deviations excess at 125 GeV/c^2

Evidence supporting the Higgs boson behaving as predicted by the Standard Model

First study of Higgs spin-parity in quark decay channels

Abstract

We show the latest results from the CDF and D0 collaborations on the study of the Higgs boson, stemming from the analysis of the entire Tevatron Run\,II dataset. Combining the results of many individual analyses, most of which use the full data set available, an excess with a significance of approximately three standard deviations with respect to the Standard Model hypothesis is observed at a Higgs boson mass of 125\,GeV/$c^2$. The Tevatron unique environment allows in addition to study for the first time the spin-parity hypothesis of the Higgs boson in events where it decays to quarks. Within the current experimental uncertainties, the newly discovered boson behaves as expected by the SM in the fermionic sector.
