A measurement of the production processes of the recently discovered Higgs boson is performed in the two-photon final state using 4.5 fb−1 of proton–proton collisions data at √ s = 7 TeV and 20.3 fb−1 at √ s = 8 TeV collected by the ATLAS detector at the Large Hadron Collider. The number of observed Higgs boson decays to diphotons divided by the corresponding Standard Model prediction, called t...

1550-7998=20 We compute the inclusive and differential cross sections for the associated production of a top quark along with a charged Higgs boson at hadron colliders to next-to-leading order (NLO) in perturbative quantum chromodynamics (QCD) and in supersymmetric QCD. For small Higgs boson masses we include top-quark pair production diagrams with subsequent top-quark decay into a bottom quark...

We present the first search at the Tevatron for a Higgs boson decaying to an invisible final state. We use the full CDF Run II data set corresponding to 9.7 fb−1 of integrated luminosity. We search in the associated ZH production mode and require two same-flavor, oppositely charged leptons and a significant value of missing transverse energy to be in the final state. We exclude values of σZH×B ...

We compute the 3-loop O(ααs) correction to the Higgs boson production cross section arising from light quarks using an effective theory approach. Our calculation probes the factorization of QCD and electroweak perturbative corrections to this process. We combine our results with the best current estimates for contributions from top and bottom quarks to derive an updated theoretical prediction f...

The radiative corrections of the strong and electroweak interactions are calculated at next-to-leading order for Higgs-boson production in the weak-boson-fusion channel at hadron colliders. Specifically, the calculation includes all weak-boson fusion and quark– antiquark annihilation diagrams to Higgs-boson production in association with two hard jets, including all corresponding interferences....

The LHC and a future linear collider are widely regarded as an ideal combination of experiments to understand electroweak symmetry breaking, i.e. study the Higgs boson and measure its couplings to all Standard Model bosons and fermions. According to the electroweak precision data [1] we expect to discover and identify a light Standard Model Higgs boson at the LHC [2, 3, 4]. At the ILC we will b...

Nobody knows exactly what kind of Higgs physics will be unveiled when the Large Hadron Collider is turned on. There could be one Standard Model Higgs boson or five Higgs bosons as is the case in two-Higgs-doublet models; there could be more exotic or even completely unexpected scenarios. In order to be prepared for the LHC era, a solid understanding of Standard Model or Standard-Model-like Higg...

We combine results from CDF and D0's direct searches for the standard model (SM) Higgs boson (H) produced in p¯ p collisions at the Fermilab Tevatron at √ s = 1.96 TeV. The results presented here include those channels which are most sensitive to Higgs bosons with mass between 130 and 200 GeV/c 2 , namely searches targeted at Higgs boson decays to W + W − , although acceptance for decays into τ...

This article reports on a search for dark matter pair production in association with a Higgs boson decaying to a pair of bottom quarks, using data from 20.3 fb−1 of pp collisions at a center-of-mass energy of 8 TeV collected by the ATLAS detector at the LHC. The decay of the Higgs boson is reconstructed as a high-momentum bb̄ system with either a pair of small-radius jets, or a single large-radi...

The dominance of h → ηη decay mode for the intermediate mass Higgs boson is highly motivated to solve the little hierarchy problem and to ease the tension with the precision data. However, the discovery modes for mh ∼ 150 GeV, h → γγ and W/Zh → (lν/ll̄)(bb̄), will be substantially affected. We show that h → ηη → 4b is complementary and we can use this decay mode to detect the intermediate Higgs b...
