Book excerpt: We present the latest CDF searches for the Standard Model Higgs boson with 1.96 TeV center-of-mass energy collisions produced at the Fermilab Tevatron. The data was collected with the CDF II detector at the Tevatron collider and correspond to an integrated luminosity from 2 to 4.8 1/fb. To achieve maximal sensitivity, many channels are analyzed including final states from gluon fusion, vector boson fusion, and associated production with W and Z bosons.

Book excerpt: The Standard model of electroweak interactions (SM) has been extremely successful in describing interactions of elementary particles over the last decades. The Higgs scalar boson is one of the key elements of the SM: Higgs interactions with the other particles generate the particle masses and allow to keep the theory renormalizable at electroweak scale. All the particles predicted by the SM but the Higgs boson have already been observed experimentally and therefore search for the Higgs is one of the most important scientific goals for high energy physics. The current lower limit on the SM Higgs mass M{sub H}> 114.4 GeV at 95% CL has been established by LEP experiments. In this paper we review CDF Run I results on Higgs searches including the Higgs bosons predicted by the minimal supersymmetric extention of the Standard Model (MSSM) and discuss the Run II prospects.

Book excerpt: We present the latest combination of searches for a standard model (SM) Higgs boson in p{bar p} collisions at (square root)s = 1.96 TeV recorded by the CDF II detector at the Fermilab Tevatron. Using data corresponding to 2.3-5.9 fb−1 of integrated luminosity, we perform searches in a number of different production and decay modes and then combine them to improve sensitivity. No excess in data above that expected from backgrounds is observed; therefore, we set upper limits on the production cross section times branching fraction as a function of the SM Higgs boson mass (m{sub H}). The combined observed (expected) limit is 1.9 (1.8) times the SM prediction at m{sub H} =115 GeV/c2 and 1.0 (1.1) times the SM prediction at m{sub H} = 165 GeV/c2.

Available in PDF, EPUB and Kindle. Book excerpt: We present the results on the searches for the SM and the MSSM Higgs boson production in proton-antiproton collisions at {radical}s = 1.96 GeV with the CDF detector. The Higgs bosons are searched for in various production and decay channels, with data samples corresponding to 400 pb{sup -1}. Using these measurements, we set an upper limit on the production cross section times branching fraction for the Standard Model Higgs as a function of the Higgs mass, and we obtain exclusion regions in the tan{beta} vs mass for the neutral MSSM Higgs, and branching fraction vs mass for the charged Higgs.

Book excerpt: Advanced analysis techniques together with increasing data samples are bringing the sensitivity of CDF to the Higgs boson very close to the SM predictions. These improvements translate into more stringent exclusions of parameter space in BSM Higgs sectors and of the SM mass range. The CDF Collaboration has a very active program on Higgs searches that comprises most accessible production mechanisms and decay channels in {bar p}p collisions at (square root)s = 1.96 TeV. This contribution will also review the combination of the different channels, data samples and analysis techinques that currently produces one of the most exciting experimental results in our field.

Book excerpt: We present the results on the searches for the SM and the non-SM Higgs boson production in p{bar p} collisions at {radical}s = 1.96 TeV with the CDF detector at the Fermilab Tevatron. Using data corresponding to 300-700 pb{sup -1}, we search for the Higgs boson in various production and decay channels. No signal is observed, therefore, we set upper limits on the production cross-section times branching fraction as a function of the Higgs boson mass.

Available in PDF, EPUB and Kindle. Book excerpt: The Higgs boson is the only elementary particle predicted by the Standard Model (SM) that has neither been confirmed nor refuted. The CDF collaboration has performed SM Higgs searches in many channels using p{bar p} collisions at a centre-of-mass energy √s = 1.96 TeV. We present the latest combined Higgs boson search at CDF. Since the previous year's combination, the sensitivity is increased through the addition of new channels, the improvement of existing channels and the addition of new data samples. We also use the latest parton distribution functions and gg → H theoretical cross sections when modelling the signal event yields. Using integrated luminosities of up to 8.2 fb−1, we observe a good agreement between data and the background prediction. Since we do not see a Higgs boson excess, we set 95% CL upper limits on the Higgs boson cross section in the range between 100 and 200 GeV/c2, with 5 GeV/c2 increments. The observed (expected) limits for a 115 and a 165 GeV/c2 Higgs boson are 1.55 (1.49) and 0.75 (0.79) x SM, respectively. Since last year, the Higgs boson excluded range by CDF is extended to 156.5 - 173.7 and 100 - 104.5 GeV/c2.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We combine results from CDF and D0 on direct searches for the standard model (SM) Higgs boson (H) in p{bar p} collisions at the Fermilab Tevatron at √s = 1.96 TeV. Compared to the previous Tevatron Higgs boson search combination more data have been added, additional channels have been incorporated, and some previously used channels have been reanalyzed to gain sensitivity. We use the MSTW08 parton distribution functions and the latest theoretical cross sections when comparing our limits to the SM predictions. With up to 8.2 fb−1 of data analyzed at CDF and up to 8.6 fb−1 at D0, the 95% C.L. our upper limits on Higgs boson production are factors of 1.17, 1.71, and 0.48 times the values of the SM cross section for Higgs bosons of mass m{sub H} = 115 GeV/c2, 140 GeV/c2, and 165 GeV/c2, respectively. The corresponding median upper limits expected in the absence of Higgs boson production are 1.16, 1.16, and 0.57. There is a small (≈ 1[sigma]) excess of data events with respect to the background estimation in searches for the Higgs boson in the mass range 125

Available in PDF, EPUB and Kindle. Book excerpt: A search for a low-mass SM Higgs-Boson in the channel WH → lvb$\bar{b}$ has been performed using neural networks. The data were taken by the CDF experiment at the p-$\bar{p}$ collider Tevatron from 2000-2003, corresponding to in integrated luminosity of Lint = 162 pb-1 at a CMS-energy of √s = 1.96 TeV. 95% confidence level upper limits are set on [sigma] × BR, the product of the production cross section times the Branching ratio, as a function of the Higgs boson mass. Cross sections above 8 pb are excluded for six different Higgs masses between 110 GeV/c2 and 150 GeV/c2. The required integrated luminosities for a 95% C.L. exclusion, 3[sigma] evidence and 5[sigma] discovery are calculated.

Available in PDF, EPUB and Kindle. Book excerpt: These proceedings present the most up-to-date status of deep inelastic scattering (DIS) physics. Topics such as structure function measurements and phenomenology, quantum chromodynamics (QCD) studies in DIS and photoproduction, spin physics and diffractive interactions are reviewed in detail, with emphasis on those studies that push the test of QCD and the Standard Model to the limits of their present range of validity, towards both the very high and the very low four-momentum transfers in leptonproton scattering.
