    Higgs(general) at ATLAS

    Full text link
    The ATLAS Higgs results are reviewed using Run-2 data taken at a center-of-mass energy of 13 TeV with up to an integrated luminosity of 80 fb−1^{-1}. So far, the data are consistent with the standard model expectations. ATLAS now has observed the Higgs Yukawa coupling to the third generation fermions with H→ττH\rightarrow \tau\tau, ttH, and H→bbH\rightarrow b b in the VH process. The Higgs boson will continue to provide an important probe for new physics and beyond.Comment: Proceeding for International Workshop on Top Quark Physics, Bad Neuenahr, Germany September 16-21 2018. 5 pages with 9 figure

    We present the recent results on the search for the low mass Higgs boson at the Tevatron by the CDF and DØ Collaborations. With up to 5.9 fb−1 of data analyzed at CDF and up to 6.7 fb−1 at DØ, the 95% C.L. upper limits on Higgs boson production are factors of 1.56 times the values of the standard model cross section for a Higgs boson mass of mH = 115GeV/c2

    Standard Model Higgs Boson Combination at the Tevatron

    We present the recent results from combinations of searches for a standard model (SM) Higgs boson (HH) by the CDF and D0 experiments at the Tevatron ppˉp\bar p collider at s=1.96\sqrt{s}=1.96 TeV. The data correspond to an integrated total luminosity of 8.2 (CDF) and 8.6 (D0) fb−1^{-1}. Compared to the previous Tevatron Higgs boson search combination more data have been added, additional channels have been added, and some previously used channels have been reanalyzed to gain sensitivity. No excess is observed above background expectation, and set 95% C.L. upper limits (median expected) on Higgs boson production at factors of 1.17 (1.16), 1.71 (1.16), and 0.48(0.57) times the SM predictions for Higgs bosons of mass mHm_H=115, 140, and 165 GeV/c2^2, respectively. We exclude a standard-model Higgs boson in the mass range 156--177 GeV/c2^2 at the 95% C.L, with an expected exclusion region 148--180 GeV/c2^2. The absence of a Higgs boson signal also constrains some new physics such as 4th4^{th} generation models and other exotic models.Comment: Presented at the 2011 Hadron Collider Physics Symposium (HCP-2011), Paris, France, November 14-18 2011, 4pages, 8 figure
