I12.00001: Search for Higgs Boson Production via the Process $p\bar{p}\rightarrow ZH \rightarrow l^{+}l^{-}b\bar{b}$ at CDF Ben Kilminster, Jonathan Efron, Brian Winer, Richard Hughes, Beate Heinemann, Andrew Mehta We are conducting a search for the Higgs boson via the process $p\bar{p}\rightarrow ZH\rightarrow l^{+}l^{-} b\bar{b}$ using \~700~$pb^{-1}$ of data from CDF Run 2. The Higgs Boson is predicted by the Standard Model but has yet to be observed. The main background of this ZH signal is Z + jets, where the Z decays into two charged leptons. The signal is distinguished from the backgrounds using an artificial neural network. We will report on the status of the search and the future prospects using the anticipated large data samples from Run 2. [Preview Abstract] |

I12.00002: CMS Detector Sensitivity to the Standard Model Higgs Boson in $H \rightarrow ZZ \rightarrow 4\mu$ Decay Channel Alexei Drozdetski, D. Acosta, P. Bartalini, R. Cavanaugh, A. Korytov, G. Mitselmakher, B. Scurlock, Yu. Pakhotin, M. Aldaya, P. Arce, J. Caballero, B. Cruz, P. Garcia, J. Hernandez, I. Josa, E.R. Morales, A. Sherstnev, S. Abdullin Presented are the results of the analysis of the CMS detector sensitivity to the Standard Model Higgs boson in its 4-muon decay channel, $H \rightarrow ZZ \rightarrow 4\mu$, in the Higgs boson mass range from 115-600 GeV. The studies are based on the most recent full CMS detector simulation and mimic the real data analysis with the most critical calibrations extracted from ``data'' and all systematic uncertainties explicitly evaluated and taken into account.

I12.00003: A Study of $H \rightarrow WW^* \rightarrow l \nu jj$ at CMS Heejong Kim, N. Akchurin, J. Damgov, S. Kunori, H. Pi, E. Yazgan One of the most challenging channels for observing Higgs boson production at the Large Hadron Collider (LHC) is a Higgs which is produced via the Vector Boson Fusion process and which then decays $H \rightarrow WW^{*} \rightarrow \ell \nu jj$ ($\ell$ is an electron or muon, j is a jet). We present results of a study of the sensitivity of the CMS experiment for this process, assuming Higgs mass at 120 $GeV/c^2$. [Preview Abstract] |

I12.00004: Search for Standard Model Higgs Boson Production in Association with $W^{\pm}$ Bosons at CDF Yoshiaki Kusakabe We present a search for the Standard Model Higgs boson decaying into $b\bar{b}$ after being produced in association with a $W^{\pm}$ boson in the $p\bar{p}$ collisions at $\sqrt{s}=1.96$~TeV. The search uses the data collected up to fall 2005 using the CDF detector, which corresponds to an integrated luminosity of about 700~$pb^{-1}$. Events with an electron or muon, large missing transverse energy and jets are selected using an advanced multivariate technique and at least one of the jets is required to be $b$-tagged for further reduction of the large $W^{\pm}+$jet background. We set a limit on the $p\bar{p}\rightarrow W^{\pm}H$ production cross section. [Preview Abstract] |

I12.00005: Search for Associated Production of W and Higgs Bosons at D\O Venkatesh Kaushik We present preliminary results of $Wb\bar{b}$ production and a search for the Higgs boson through its associated production with W for masses between 105 and 150 GeV in $p\bar{p}$ collisions at $\sqrt{s}$ = 1.96 TeV. The search is performed in events containing one election, an imbalance in the transverse enegy($E_T$) and two $b$-tagged jets in $\approx$1$fb^{-1}$ of integrated luminosity accumulated by the D\O\ experiment at Fermilab.

I12.00006: Search for Associated Production of Z and Higgs Bosons in $e^+e^-b\bar{b}$ final states James Heinmiller Studies are presented of the search for a light Standard Model Higgs boson produced in association with a $Z$ boson in the $Z \rightarrow e^+e^-$ and $h \rightarrow b\bar{b}$ decay channel using Run II data collected by the D\O\ detector at the Fermilab $p\bar{p}$ collider at $\sqrt{s} = 1.96$ TeV. We also present our current understanding of the most significant background to this process, namely the QCD production of $b\bar{b}$ associated with the Z boson. [Preview Abstract] |

I12.00007: Search for Associated Production of Z and Higgs Bosons in $\mu^+\mu^-b\bar{b}$ final states Huishi Dong We present the preliminary studies on the search for a light mass Standard Model Higgs Boson produced in association with a Z boson in the $\mu^+\mu^-b\bar{b}$ channel at D\O\ Run II. With the available recorded luminosity more than three times the Run I luminosity, we also present our current understanding of the most significant background to this process, namely the QCD production of $b\bar{b}$ associated with the Z boson.

I12.00008: Search for Associated Production of Z and Higgs Bosons in $\nu \bar{\nu}b\bar{b}$ Final States Michele Petteni Studies are presented from the D\O\ experiment at Fermilab for the search for a light Standard Model Higgs Boson in association with a $Z $ boson, which decays invisibly to $\nu\bar{\nu}$. This channel relies on the identification of two $b$-tagged jets from the Higgs Boson decay and on the measurement of a large imbalance in the transverse energy ($E_T$) of the event. This channel is challenging as the decay signatures are common in QCD and instrumental backgrounds. [Preview Abstract] |

I12.00009: Search for Higgs Boson in $WW^{(*)}$ Decays Maxim Titov The process $H \rightarrow WW^{(*)} \rightarrow \ell^+ \ell^- \,(\ell = e, \mu)$ is studied in $p\bar{p}$ collisions at the center of mass energy $\sqrt{s} = 1.96$ TeV with the upgraded D\O\ detector at the Fermilab Tevatron accelerator. A Higgs particle with a mass greater than 140 GeV primarily decays into a of W-bosons and the semi-leptonic decay channels of the W provide a clear signature. Apart from the Standard Model Higgs, for which a discovery will only be possible at highest integrated luminosities, exotic models with enhanced cross sections may be probed already with data corresponding to integrated luminosities of a few hundred pb$^{-1}$.
