We study Higgs boson production and decay in a certain class of Little Higgs models with T-parity in which some T-parity partners of the Standard Model (SM) fermions gain their masses through Yukawa-type couplings. We find that the Higgs boson production cross section of a 120 GeV Higgs boson at the CERN LHC via gg fusion process at one-loop level could be reduced by about 45%, 35% and 20%, as ...

We present a search for the standard model Higgs boson produced in association with a W boson in sqrt[s]=1.96  TeV pp collision data collected with the CDF II detector at the Tevatron corresponding to an integrated luminosity of 9.45  fb(-1). In events consistent with the decay of the Higgs boson to a bottom-quark pair and the W boson to an electron or muon and a neutrino, we set 95% credibilit...

We combine searches by the CDF and D0 Collaborations for the associated production of a Higgs boson with a W or Z boson and subsequent decay of the Higgs boson to a bottom-antibottom quark pair. The data, originating from Fermilab Tevatron pp collisions at √s = 1.96 TeV, correspond to integrated luminosities of up to 9.7 fb(-1). The searches are conducted for a Higgs boson with mass in the rang...

Precise measurements of the mass and width of the W boson are carried out in e + e − collisions at Lep, by kinematic reconstruction of the invariant mass distributions of W + W − → qq ′ ℓν ℓ and W + W − → qq ′ qq ′ candidate events. The most recent combination of such results from Aleph, Delphi, L3 and Opal uses approximately 82% of the final Lep2 integrated luminosity and is preliminary. The m...

The W mass is a crucial parameter in the Standard Model (SM) of particle physics, providing constraints on the mass of the Higgs boson as well as on new physics models via quantum loop corrections. On the other hand, any deviation of the triple gauge boson couplings (TGC) from their values predicted by the SM would be also an indication for new physics. We present recent measurements on W boson...

Real emission corrections to gg→H, which lead to H +2 jet events, are calculated at order αs. Contributions include top-quark triangles, boxes and pentagon diagrams and are evaluated analytically for arbitrary top mass mt. This new source of H +2 jet events is compared to the weak-boson fusion cross section for a range of Higgs boson masses. The heavy top-mass approximation appears to work well...

We use (fermion) mass perturbation theory for the massive Schwinger model to compute the boson-boson bound state mass in lowest order. For small fermion mass the lowest possible Fock state turns out to give the main contribution and leads to a second order result for the bound state mass. ∗)permanent address: Institut für theoretische Physik, Universität Wien Boltzmanngasse 5, 1090 Wien, Austri...

The Standard Model fit prefers values of the Higgs Boson mass mH that are below the 114 GeV direct lower limit from LEP II. The discrepancy is acute if the 3.2σ disagreement for sinθ` eff W from the two most precise measurements is attributed to underestimated systematic error. In that case the data suggests new physics to raise the predicted value of mH . One of the simplest possibilities is a...

We have used detailed Monte Carlo simulations to study search strategies for Higgs bosom at high energy e+ecolliders. We extend an earlier study of the minimal single-Higgs-doublet model at a center-of-mass energy of 1 TeV to examine the effects of b-quark tagging and jet counting. It is found that these techniques can increase the signal-to-noise ratio substantially in the mass range around th...

We present explicit analytic results for the two-loop top/stop/gluino contributions to the cross section for Higgs boson production via gluon fusion in the MSSM, under the approximation of neglecting the Higgs boson mass with respect to the masses of the particles circulating in the loops. The results are obtained employing the low-energy theorem for Higgs interactions adapted to the case of pa...
