Inflation scenario via the Standard Model Higgs boson and LHC
Barvinsky, A. O.;Kamenshchik, A. Yu.;Starobinsky, A. A.
High Energy Physics - Phenomenology , 2008, DOI: 10.1088/1475-7516/2008/11/021
Abstract: We consider a quantum corrected inflation scenario driven by a generic GUT or Standard Model type particle model whose scalar field playing the role of an inflaton has a strong non-minimal coupling to gravity. We show that currently widely accepted bounds on the Higgs mass falsify the suggestion of the paper (where the role of radiative corrections was underestimated) that the Standard Model Higgs boson can serve as the inflaton. However, if the Higgs mass could be raised to $\sim 230$ GeV, then the Standard Model could generate an inflationary scenario with the spectral index of the primordial perturbation spectrum $n_s\simeq 0.935$ (barely matching present observational data) and the very low tensor-to-scalar perturbation ratio $r\simeq 0.0006$.
THE PHYSICS OF THE STANDARD MODEL HIGGS BOSON AT THE LHC  [PDF]
DIRK GRAUDENZ
Physics , 1995,
Abstract: Some topics related to Standard Model Higgs boson physics at the Large Hadron Collider are reviewed. Emphasis is put on an overview of QCD corrections to Higgs boson decay and production processes. (Invited talk presented at the XXXth Rencontres de Moriond, Les Arcs 1800, March 19-26, 1995; to appear in the proceedings of the conference.)
The ALEPH Search for the Standard Model Higgs Boson  [PDF]
J. A. Kennedy
Physics , 2001,
Abstract: A search has been performed for the Standard Model Higgs boson in the data collected with the ALEPH detector in 2000. An excess of 3 sigma above the background expectation is found. The observed excess is consistent with the production of the Higgs boson with a mass close to 114 GeV/c2.
Standard Model Higgs boson searches at the Tevatron  [PDF]

Physics , 2014, DOI: 10.1142/S0217732314300092
Abstract: We give an overview of Standard Model Higgs boson studies performed at the CDF and Dzero experiments at the Tevatron proton-antiproton collider. Combining the results of many individual analyses, most of which use the full data set available, an excess with a significance of 3.0 standard deviations with respect to the Standard Model hypothesis is observed at a Higgs boson mass of 125 GeV/$c^2$. At that mass, the combined best-fit cross section is consistent with the Standard Model prediction. Constraints are also placed on the Higgs boson couplings with fermions and electroweak vector bosons and are consistent with the Standard Model predictions within the uncertainties.
Standard Model Higgs Boson Searches at the Tevatron  [PDF]
Kyle J. Knoepfel
Physics , 2013,
Abstract: Updated Standard Model Higgs boson search results from the Tevatron experiments are presented. We focus on the updated CDF MET+bb result, where a significant shift in observed limits is explained. For the Tevatron combinations, upper limits at 95% credibility level and best-fit values for the Higgs boson cross section times branching ratio are presented. We also place constraints on the Higgs couplings to fermions and electroweak vector bosons. All results are consistent with the existence of a Standard Model Higgs boson with a mass of 125 GeV/c2, and with the Standard-Model predictions associated with that assumption.
The Standard Model Intermediate Mass Higgs Boson  [PDF]
S. Dawson
Physics , 1997,
Abstract: We consider the phenomenology of the Standard Model intermediate mass Higgs boson, $71 GeV < M_h < 2 M_W$. The motivation for a Higgs boson in this mass region is emphasized. The branching ratios for the Higgs boson, including electroweak and QCD radiative corrections, are presented, along with production cross sections for $e^+e^-, \mu^+\mu^-, \gamma\gamma$, and hadronic interactions. Search strategies are surveyed briefly.

Search for the Standard Model Higgs Boson at LEP  [PDF]
ALEPH Collaboration,DELPHI Collaboration,L3 Collaboration,OPAL Collaboration,the LEP Higgs Working Group
Physics , 2001,
Abstract: The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have collected 2465 pb-1 of e+e- collision data at energies between 189 and 209 GeV, of which 542 pb-1 were collected above 206 GeV. Searches for the Standard Model Higgs boson have been performed by each of the LEP collaborations. Their data have been combined and examined for their consistency with the Standard Model background and various Standard Model Higgs boson mass hypotheses. A lower bound of 114.1 GeV has been obtained at the 95% confidence level for the mass of the Higgs boson. The likelihood analysis shows a preference for a Higgs boson with a mass of 115.6 GeV. At this mass, the probability for the background to generate the observed effect is 3.4%.
Search for the Standard Model Higgs Boson at LEP  [PDF]
Andre G. Holzner
Physics , 2002, DOI: 10.1016/S0920-5632(02)02021-2
Abstract: One of the missions of the LEP program was the search for the Standard Model Higgs Boson. The skillful operation of the machine in the year 2000, the final year of operation, has allowed the four collaborations ALEPH, DELPHI, L3 and OPAL to collect 536/pb of data at center-of-mass energies of 206 GeV or higher. This data is used to probe the existence of the Higgs boson up to a mass of around 115 GeV. Tantalizing candidates have been observed in excess over the Standard Model predictions, but without enough statistical power to claim a discovery. A Higgs boson lighter than 114.4 GeV is hence excluded at 95% confidence level.
Search for the Standard Model Higgs Boson at LEP  [PDF]
G. Abbiendi
Physics , 2003, DOI: 10.1016/S0370-2693(03)00614-2
Abstract: The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have collected a total of 2461 pb-1 of e+e- collision data at centre-of-mass energies between 189 and 209 GeV. The data are used to search for the Standard Model Higgs boson. The search results of the four collaborations are combined and examined in a likelihood test for their consistency with two hypotheses: the background hypothesis and the signal plus background hypothesis. The corresponding confidences have been computed as functions of the hypothetical Higgs boson mass. A lower bound of 114.4 GeV/c2 is established, at the 95% confidence level, on the mass of the Standard Model Higgs boson. The LEP data are also used to set upper bounds on the HZZ coupling for various assumptions concerning the decay of the Higgs boson.
