The standard model (SM) predicts the existence of one scalar particle, the Higgs boson (H). The Higgs boson is the only particle of the SM which has not been found until now. Electroweak precision data mainly collected at CERN LEP and SLAC SLC in combination with the direct top-quark mass measurement at the Tevatron would favour a light Higgs boson with a mass below about 200 GeV at the 95% con...

Abstract: In this paper, we analyze the high-energy limits for Higgs boson + two jet production. We consider two high-energy limits, corresponding to two different kinematic regions: (a) the Higgs boson is centrally located in rapidity between the two jets, and very far from either jet; (b) the Higgs boson is close to one jet in rapidity, and both of these are very far from the other jet. In bo...

We review the standard Higgs boson physics and the search for standard Higgs boson at LEP and LHC supercolliders

The Higgs boson search has shifted from LEP2 to the Tevatron and will subsequently move to the LHC. Due to the different initial states, the Higgs production and decay channels relevant for Higgs boson searches were different at LEP2 to what they are at hadron colliders. We suggest new benchmark scenarios for the MSSM Higgs boson search at hadron colliders that exemplify the phenomenology of di...

The decay rate of a (neutral) Higgs boson (H) going into a longitudinal W -boson pair is calculated by including one loop radiative corrections in a two-Higgs doublet model. It is assumed that the Higgs boson H is much heavier than the W boson and a full use has been made of the equivalence theorem. A possibility is explored extensively that the precise measurement of the decay rate of H could ...

The discovery of the Higgs boson is remarkable for its importance in modern Physics research. The next step for physicists is to discover more about the Higgs boson from the data of the Large Hadron Collider (LHC). A fundamental and challenging task is to extract the signal of Higgs boson from background noises. The machine learning technique is one important component in solving this problem. ...

Recent results obtained by the CDF and DØ collaborations are presented here. These Tevatron Higgs searches look for a Standard Model (SM) Higgs boson decaying into W-boson pairs, with the W-bosons decaying into electron-neutrino or muon neutrino final states. In the mass range of 135 GeV/c to 200 GeV/c, the SM Higgs decays prominently into W-boson pairs. The presented results are based on an in...

We quantify the extent to which naturalness is lost as experimental lower bounds on the Higgs boson mass increase, and we compute the natural upper bound on the lightest supersymmetric Higgs boson mass. We find that it would be unnatural for the mass of the lightest supersymmetric Higgs boson to saturate it’s maximal upper bound. In the absence of significant fine-tuning, the lightest Higgs bos...

Any new scalar fields that perturbatively solve the hierarchy problem by stabilizing the Higgs boson mass also generate new contributions to the Higgs boson field-strength renormalization, irrespective of their gauge representation. These new contributions are physical, and in explicit models their magnitude can be inferred from the requirement of quadratic divergence cancellation; hence, they ...

Vector-boson fusion (VBF) processes have emerged as a particularly interesting class of scattering events from which one hopes to gain insight into the dynamics of electroweak symmetry breaking. The most prominent example is Higgs boson production via VBF, which is shown in Fig. 1. This process has been studied intensively as a tool for Higgs boson discovery [1–3] and the measurement of Higgs b...
