146. Measurement of properties of the Higgs boson in bosonic decay channels using the ATLAS detectorKate Whalen (Carleton University (CA))05/05/2014, 14:00A detailed review will be given of the latest results from the ATLAS detector on the main properties of the Higgs boson in the diphoton, $ZZ$ (with subsequent decays to four leptons), $WW$ (with subsequent decays to $\ell\nu\ell\nu$), and Z$\gamma$ channels using approximately 25 fb$^{-1}$ of $pp$ collision data collected at 7 TeV and 8 TeV in 2011 and 2012. The measurements discussed will be...Go to contribution page

Yuki Sakurai (Waseda University (JP))05/05/2014, 14:15Since the discovery of the Higgs boson by the ATLAS and CMS experiments at the LHC, the emphasis has shifted towards measurements of its properties. Of particular importance is the direct observation of the coupling of the Higgs boson to fermions. In this presentation a comprehensive review of ATLAS results in the search for the Higgs boson in tau, muon, and b-quark pairs will be given.Go to contribution page

James Saxon (University of Pennsylvania (US))05/05/2014, 14:30Properties of Higgs boson production are presented, as measured by the ATLAS detector at the LHC in 2011 and 2012. Couplings and spin measurements are reviewed briefly. Limits on the invisible and unobserved branching fractions are presented, from direct searches and combined fits. Differential cross sections measured in the diphoton decay channel provide additional information about the...Go to contribution page

Fady Bishara (U. of Cincinnati & Fermilab)05/05/2014, 14:45We explore the sensitivity of the $pp\rightarrow W^\pm W^\pm jj$ process to deviations of the Higgs-vector coupling from its SM value. Since the Higgs-mediated contribution does not depend on other Higgs couplings and is independent of the total Higgs width to a good approximation, we can probe the Higgs-vector coupling directly. In the standard model, the Higgs channel does not give a...Go to contribution page

Mr Yaofu Zhou (JHU)05/05/2014, 15:00We study the extent to which CP parity of a Higgs boson, and more generally its anomalous couplings to gauge bosons, can be measured at the LHC and a future electron-positron collider. We consider several processes, including Higgs boson production in gluon and weak boson fusion and production of a Higgs boson in association with an electroweak gauge boson. We consider decays of a Higgs boson...Go to contribution page

Donald Austin Belknap (University of Wisconsin (US))05/05/2014, 15:15The CMS results are presented for an analysis of the mass, width, and spin-parity properties of a Higgs boson candidate near 126 GeV in the $ZZ\to 4l$ channel, with $l=\mu,e$. The analysis utilizes the full dataset recorded by CMS of 5.1 $\text{fb}^{-1}$ and 19.7 $\text{fb}^{-1}$ of LHC $pp$ collisions at a center-of-mass energy of $\sqrt{s} = 7$ and 8 TeV respectively. The mass is measured to...Go to contribution page

Arnaud Pin (Universite Catholique de Louvain (UCL) (BE))05/05/2014, 15:30A search for the Standard Model (SM) Higgs boson decaying to bottom quark pairs is presented. Three different production mechanisms for the Higgs boson have been investigated: the vector boson fusion (VBF), the associated production with a W or Z boson decaying leptonically (VH) and the associated production with pair of top quarks (ttH). These searches are based on data collected with the CMS...Go to contribution page

Anthony Rose (Texas A & M University (US))05/05/2014, 15:45A search for the associated production of a W boson and the standard model Higgs boson, which decays into a pair of hadronically decaying tau leptons, is presented using data collected in 2011 and 2012 by the CMS experiment. The analysis uses 5 fb−1 and 19 fb−1 collision data collected at the center-of-mass energies of 7 TeV and 8 TeV, respectively. The analysis motivation, procedure and...Go to contribution page
