Review of Physics Results from the Tevatron: Higgs Boson Physics

Abstract

We review the techniques and results of the searches for the Higgs boson performed by the two Tevatron collaborations, CDF and DØ. The Higgs boson predicted by the Standard Model was sought in the mass range 90 GeV< m H < 200 GeV in all main production modes at the Tevatron: gluon-gluon fusion, W H and ZH associated production, vector boson fusion, and t tH production, and in five main decay modes: * ) , and H → γγ. An excess of events was seen in the H → b b searches consistent with a Standard Model Higgs boson with a mass in the range 115 GeV< m H <135 GeV. Assuming a Higgs boson mass of m H = 125 GeV, studies of Higgs boson properties were performed, including measurements of the product of the cross section times the branching ratio in various production and decay modes, constraints on Higgs boson couplings to fermions and vector bosons, and tests of spin and parity. We also summarize the results of searches for supersymmetric Higgs bosons, and Higgs bosons in other extensions of the Standard Model.

Status of the MSSM Higgs sector using global analysis and direct search bounds, and future prospects at the High Luminosity LHC

“…Both the ATLAS and CMS collaborations have published the results of the 125 GeV Higgs boson searches combining the 7+8 TeV data at the end of 8 TeV run of LHC [6][7][8][9][10][11][12][13][14][15][16][17]. Besides, the results of the SM Higgs boson search by the CDF and D∅ collaborations at the Tevatron experiment are also available in the literature [3,68]. In our global analysis, we consider the most updated Higgs data obtained from the LHC and Tevatron experiments.…”

“…However, there exist other sub-dominant production mechanisms e.g., vector boson fusion (VBF), associated production with a W/Z boson (Vh), associated production with a pair of top quarks (t th). The decay modes of the Higgs boson which are analyzed by the ATLAS and CMS collaborations are h → γγ [6,7], h → W W * [8,9], h → ZZ * [10,11], h → b b [12,13], and h → τ + τ − [14,15], while the CDF and D∅ collaborations have analyzed the γγ, W W * and b b decay modes of the Higgs boson [3,68]. The experimental findings are usually presented in terms of the signal strength variable (µ), which is defined as the ratio of the production cross section (σ) times the branching ratio (Br) to a specific decay mode for a given new physics model normalized to the SM prediction.…”

“…We do not consider any specific SUSY breaking scenario, rather we focus on the generic phenomenological MSSM (pMSSM) model with 19 free parameters and perform a random scan for approximately 100 million points. Those parameters that are relevant to the MSSM Higgs sector, namely pseudo-scalar mass parameter M A , the ratio of the vacuum expectation values of two Higgs doublets tan β, higgsino [3,68]. The amount of contribution to a given channel from each production modes are shown in Column 4-6.…”

Particle physics after the Higgs boson discovery: opportunities for the Large Hadron Collider

“…4 A review of Higgs-boson searches at the Tevatron is given in Ref. [42]. 5 Luminosity, expressed in cm −2 s −1 , is a convenient measure of collision rate for colliders.…”
