چکیده

A bstract In this work we revisit the existence of a strong first order electroweak phase transition (SFOEWPT) and recent m W precision measurement in Type-I Type-II 2HDMs. The $$ \mathcal{O} O (100) GeV new scalars 2HDMs are favored by SFOEWPT, which is necessary for baryogenesis, observed shift as well. We find that under current constraints, both 2HDM can explain Z-pole, Higgs measurements CDF-II at same time, all these sensitive to heavy mass splitting 2HDM. allowed regions ? A/C ? (?400 , 400) GeV, tan ? (1 50), (?200 300) 10) respectively. Furthermore future lepton collider on Z boson properties explore scenario more detail or even rule out it.

Precise Electroweak Measurements at the Z 0 Pole B

Over the last decade, precise LEP and SLC measurements of electroweak coupling parameters at the Z 0 pole have lead to tests of the Standard Model to unprecedented precision. This report presents a comprehensive review of these studies, including a review of relevant Z 0 pole physics issues, facilities, instrumentation, and the measurements made. Global fits for the Higgs Boson mass and Z 0 − b...

Singlet-Catalyzed Electroweak Phase Transitions and Precision Higgs Studies

We update the phenomenology of gauge singlet extensions of the Standard Model scalar sector and their implications for the electroweak phase transition. Considering the introduction of one real scalar singlet to the scalar potential, we analyze present constraints on the potential parameters from Higgs coupling measurements at the Large Hadron Collider (LHC) and electroweak precision observable...

Constraints Placed on the Higgs Sector from Precision Electroweak Measurements

In this lecture, I would like to investigate what precision electroweak measurements have to tell us about the Higgs sector. I will show that the radiative corrections to electroweak interaction observables coming from the Higgs sector can be summarized into three parameters S, T, and U. The precision measurements of the observables will constrain S and 2’. By comparing these constraints with t...

Singlet Higgs Phenomenology and the Electroweak Phase Transition

We study the phenomenology of gauge singlet extensions of the Standard Model scalar sector and their implications for the electroweak phase transition. We determine the conditions on the scalar potential parameters that lead to a strong first order phase transition as needed to produce the observed baryon asymmetry of the universe. We analyze the constraints on the potential parameters derived ...

Electroweak Phase Transition in Two Higgs Doublet Models

We reexamine the strength of the first order phase transition in the electroweak theory supplemented by an extra Higgs doublet. The finite-temperature effective potential, Veff , is computed to one-loop order, including the summation of ring diagrams, to study the ratio φc/Tc of the Higgs field VEV to the critical temperature. We make a number of improvements over previous treatments, including...
