We study the observability for a Standard Model-like Higgs boson at an upgraded Tevatron via the modes pp̄ → gg → h → W W ∗ → lνjj and lν̄l̄ν. We find that with c. m. energy of 2 TeV and an integrated luminosity of 30 fb the signal may be observable for the mass range of 135 GeV <∼ mh <∼ 180 GeV at a 3 − 5σ statistical level. Taking into account the existing results in the literature, we expect th...

The weak boson fusion process for neutral Higgs boson production is investigated with particular attention to the accuracy with which the Higgs boson couplings to weak bosons can be determined in final states that contain a Higgs boson plus at least two jets at CERN Large Hadron Collider energies. We determine that an accuracy of δg/g ∼ 10% on the effective coupling g may be possible after the ...

A CP-even neutral Higgs boson with standard-model-like couplings may be the lightest scalar of a twoHiggs-doublet model. We study the decoupling limit of the most general CP-conserving two-Higgs-doublet model, where the mass of the lightest Higgs scalar is significantly smaller than the masses of the other Higgs bosons of the model. In this case, the properties of the lightest Higgs boson are n...

A Higgs boson with mass below 150 GeV has a total decay width of less than 20 MeV into accessible Standard Model states. This narrow width means that the usual branching fractions for such a light Higgs boson are highly susceptible to any new particles to which it has unsuppressed couplings. In particular, there are many reasonable and interesting theoretical ideas that naturally imply an invis...

It is unlikely that a high statistics study of r-lepton decays will be sensitive to the Higgs boson sector of electroweak physics. A Tau-Charm Factory is an ideal facility for the study of rare deca.ys of the rlepton. At a machine discussed in these Proceedings, one might expect to produce on the order of lo7 r’s per year. It is an interesting exercise to consider whether such a data sample is ...

We investigate the thermodynamics of non-relativistic and relativistic ideal gases on the spacetime with noncommutative fuzzy geometry. We first find that the heat capacities of the non-relativistic ideal boson and fermion on the fuzzy two-sphere have different values, contrast to that on the commutative geometry. We calculate the “statistical interparticle potential” therein and interprete thi...

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 ...

A summary of the Higgs boson searches by the ATLAS and CMS collabrations using 1 f b −1 of LHC data is presented, concentrating on the Standard Model Higgs boson. Both experiments have the sensitivity to exclude at 95% CL a Standard Model Higgs boson in most of the Higgs boson mass region between about 130 GeV and 400 GeV. The observed data allow the exclusion of a Higgs Boson of mass 155 GeV t...

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...

The production of W or Z bosons in association with two jets is an important background to the Higgs boson search in vector-boson fusion at the LHC. The purely electroweak component of this background is dominated by vector-boson fusion, which exhibits kinematical distributions very similar to the Higgs boson signal. We consider the next-to-leading order QCD corrections to W and Z boson product...
