Electroweak baryogenesis and the triple Higgs boson coupling
نویسنده
چکیده
We study collider signatures of electroweak baryogenesis in the two Higgs doublet model and the minimal supersymmetric standard model. It is found that the trilinear coupling of the lightest Higgs boson receive large quantum corrections if the electroweak phase transition is strongly first order for successful baryogenesis. In the two Higgs doublet model, the magnitude of the deviation from the standard model value is shown to be larger than 10%. Such a deviation can be detected at a future electron-positron linear collider.

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...
متن کاملOverview of Electroweak Baryogenesis
Clarification of the origin of the BAU is one of the greatest challenges in particle physics and cosmology. If the BAU is generated before T = O(1) MeV, the light element abundances (D,He,He,Li) can be explained by the standard Big-Bang cosmology. To get the right η (which is called baryogenesis) from an initially baryon symmetric universe, the so-called Sakharov’s conditions should be satisfie...

In this paper, an analytic treatment of electroweak phase transition is proposed within the two-Higgs doublet model. This phase transition occurs in one stage and is strongly first order. Therefore, it can be applied to the electroweak baryogenesis scenario, whereas the standard model cannot provide this condition considering the experimental data. Also, we study CP violation which is one of th...
متن کاملDoes LEP prefer the NMSSM ?
We study the naturalness of electroweak symmetry breaking and baryogenesis in the next-to-minimal supersymmetric standard model (NMSSM). Our study is motivated by the recent LEP bounds on the Higgs boson mass which severely constrains the low tan β region of the minimal supersymmetric standard model (MSSM). We show that the low tanβ region of the NMSSM is clearly favoured over the MSSM with reg...
متن کاملHiggs Boson Signatures of MSSM Electroweak Baryogenesis
Electroweak baryogenesis (EWBG) in the MSSM can account for the cosmological baryon asymmetry, but only within a restricted region of the parameter space. In particular, MSSM EWBG requires a mostly right-handed stop that is lighter than the top quark and a standard model-like light Higgs boson. In the present work we investigate the effects of the light stop on Higgs boson production and decay....
