The mixing induced time dependent CP asymmetry, direct CP asymmetry, and branching ratio in B → ΦK S in a model III 2HDM are calculated, in particular, neutral Higgs boson contributions are included. It is shown that satisfying all the relevant experimental constraints, for time dependent CP asymmetry S φK the model III can agree with the present data, S φk = −0.39±0.41, within the 1σ error, an...

We analyse a light charged Higgs boson in the 2-Higgs Doublet Model (2HDM) Type-I, when its mass satisfies condition $M_{H^{\pm}} < M_{t}+M_{b}$ and parameter space is consistent with theoretical requirements of self-consistency as well latest experimental constraints from Large Hadron Collider (LHC) other data. Over such space, wherein Standard (SM)-like state discovered at LHC 2012 heaviest C...

The global fit of the Standard Model to electroweak precision data, routinely performed by the LEP electroweak working group and others, demonstrated impressively the predictive power of electroweak unification and quantum loop corrections. We have revisited this fit in view of (i) the development of the new generic fitting package, Gfitter, allowing flexible and efficient model testing in high...

The multiple point principle (MPP) can be used to suppress non–diagonal flavour transitions and CP violation in the two Higgs doublet extension of the standard model. We discuss the quasi–fixed point scenario in the MPP inspired two Higgs doublet model which leads to the enhanced production of Higgs particles at the LHC if the MPP scale Λ ≃ 10− 100TeV. 1. Multiple point principle and custodial ...

In this work, the neutral Higgs boson pair production is analyzed at Compact Linear Collider (CLIC) to be operating center of mass energies $\sqrt{s}$=1400 GeV (stage 2) and $\sqrt{s}$=3000 3). The bosons searched for are CP-even (H) CP-odd (A) within framework two doublet model (2HDM) in range 300 < mH/A 1000 GeV. All types CP-conserving studied signal observability evaluated taking into accou...

The phenomenological analysis of an extension the Standard Model is analyzed in this manuscript. Two Higgs Doublet a simple way to incorporate second extra doublet reduce tension between experimental measurements and theoretical predictions. This model presents large signals which could guide search for new physics at hadron colliders. In particular, we study transverse momentum, rapidity angul...
