Charting the Higgs self-coupling boundaries

New Physics from Higgs Self-coupling Measurement *

Measurement of the triple Higgs boson coupling is one of the most important goals of the Higgs physics at a future ee linear collider (LC) experiment. This would provide the first direct information on the Higgs potential that is responsible for electroweak symmetry breaking. The existence of the triple Higgs coupling is a characteristic feature of the spontaneous breaking of the electroweak sy...

Sensitivity to the Higgs Self-coupling Using the ZHH Channel

The Standard Model predicts the value of the Higgs self-coupling but it cannot be measured at LHC. This measurement requires a machine such as the proposed International Linear Collider. Here, the sensitivity to the Higgs self-coupling is evaluated using the ZHH to six jets channel for a Higgs mass of 120GeV/c. Full simulation has been carried out for an integrated luminosity of 500 fb. Several...

Determining the Higgs boson self-coupling at hadron colliders

Inclusive standard model Higgs boson pair production at hadron colliders has the capability to determine the Higgs boson self-coupling l . We present a detailed analysis of the gg→HH→(W1W2)(W1W2) →( j j,n)( j j,8n) and gg→HH→(W1W2)(W1W2)→( j j,n)(,8n,9n) (, ,,8,,95e ,m) signal channels, and the relevant background processes, for the CERN Large Hadron Collider, and a future Very Large Hadron Col...

Indirect model-dependent probe of the Higgs self-coupling

Measurement of the Higgs self-coupling at JLC

We examine the double Higgs production process at JLC. We focus our attention on the measurement of the Higgs self-coupling. The sensitivity of the triple Higgs coupling measurement is discussed in the Higgs mass range 100-200 GeV and the center of mass energy to be 500 GeV-1.5 TeV. After the discovery of the Higgs boson, detailed study of the Higgs potential will be one of the important issues...
