Combining real and virtual Higgs boson mass constraints
نویسنده
چکیده
Within the framework of the standard model we observe that there is a significant discrepancy between the most precise Z boson decay asymmetry measurement and the limit from direct searches for Higgs boson production. Using methods inspired by the Particle Data Group we explore the possible effect on fits of the Higgs boson mass. In each case the central value and the 95% confidence level upper limit increase significantly relative to the conventional fit. The results suggest caution in drawing conclusions about the Higgs boson mass from the existing data.

Higgs Boson Search at Photon Collider for Mh = 140 − 190 Gev.
A Higgs boson within the mass range M H = 140 − 190 GeV can be discovered at a photon collider in the reaction γγ → W W (with real or virtual W). Quite moderate resolution in the effective mass of the W W system is required.
متن کاملIdentifying the Higgs Spin and Parity in Decays to Z Pairs
Higgs decays to Z boson pairs may be exploited to determine spin and parity of the Higgs boson, a method complementary to spin–parity measurements in Higgs-strahlung. For a Higgs mass above the on-shell ZZ decay threshold, a model-independent analysis can be performed, but only by making use of additional angular correlation effects in gluon-gluon fusion at the LHC and γγ fusion at linear colli...
متن کاملSearches and Prospects for the Standard Model Higgs Boson at the Tevatron
The Higgs boson is the only elementary scalar particle expected in the standard model (SM). Its discovery would be a major success for the SM and would provide new experimental insights into the electroweak symmetry breaking mechanism. Direct measurements at LEP have excluded a SM Higgs boson with a mass mH < 114.4 GeV at 95% C.L. but constraints from precision measurements nevertheless favor a...
متن کاملHiggs Boson Decays in the Minimal Supersymmetric Standard Model with Radiative Higgs Sector CP Violation
We re–evaluate the decays of the Higgs bosons in the minimal supersymmetric standard model (MSSM) where the tree-level CP invariance of the Higgs potential is explicitly broken by the loop effects of the third–generation squarks with CP–violating soft–breaking Yukawa interactions. This study is based on the mass matrix of the neutral Higgs bosons that is valid for arbitrary values of all the re...

A Higgs boson within the mass range M H = 140 − 190 GeV can be discovered at a photon collider in the reaction γγ → W W (with real or virtual W) with the luminosity integral about 1 fb −1. The reasonable resolution in the effective mass of the W W system is required. A discovery of the Higgs boson is one of the main goals for the next generation of colliders.
