Exploring wrong sign scenarios in the Yukawa-Aligned 2HDM

چکیده

We discuss scenarios with wrong-sign (WS) Yukawa couplings for the discovered Higgs boson in Yukawa-aligned two doublet model. In WS scenario, down-type quarks and/or charged leptons have an opposite sign as compared to those of standard model, which can be consistent current flavour data and signal strengths. The phenomenology additional bosons such a scenario significantly different from that right-sign couplings, mainly due larger mixing required case. show parameter space is excluded or explored by direct searches at high-luminosity LHC under constraints perturbative unitarity vacuum stability. particular, we find most Type-X (lepton specific) interaction special case alignment realized imposing softly-broken $\mathbb{Z}_2$ symmetry. propose multi-Higgs events pair productions smoking gun signature probe give expected number LHC.

Probing wrong-sign Yukawa couplings at the LHC and a future linear collider

We consider the two-Higgs-doublet model as a framework in which to evaluate the viability of scenarios in which the sign of the coupling of the observed Higgs boson to down-type fermions (in particular, b-quark pairs) is opposite to that of the Standard Model (SM), while at the same time all other tree-level couplings are close to the SM values. We show that, whereas such a scenario is consiste...

Living with the Wrong Sign

We describe a UV complete asymptotically fragile Lorentz-invariant theory exhibiting superluminal signal propagation. Its low energy effective action contains “wrong” sign higher dimensional operators. Nevertheless, the theory gives rise to an S-matrix, which is defined at all energies. As expected for a non-local theory, the corresponding scattering amplitudes are not exponentially bounded on ...

Implications of the Precision Data for Very Light Higgs Boson Scenarios in 2hdm(ii)

We present an up-to-date analysis of the constraints imposed bythe precision data on the (CP− conserving) Two-Higgs-Doublet Model of type II, with emphasis on the possible existence of very light neutral (pseudo)scalar Higgs boson with mass below 20–30 GeV. We show that even in the presence of such light particles, the 2HDM(II) can describe the electroweak data with precision comparable to that...

Scalar scenarios contributing to ( g − 2 ) μ with enhanced Yukawa

In this work we address contributions from scalars to (g − 2)μ. In order to provide a reasonable contribution it is necessary that either they are light or couple strongly with muons. Here we explore this last possibility. A scalar with mass of order 10 GeV gives significant contribution to (g − 2)μ if the Yukawa coupling is about 10−1. We suggest scenarios where this comes about naturally. ∗e-...

Exploring Social Media Scenarios for the Television

The use of social technologies is becoming ubiquitous in the lives of average computer users. However, social media has yet to infiltrate users‟ television experiences. This paper presents the findings of an exploratory study examining social scenarios for TV. Eleven participants took part in the three-part study that included in-home field visits, a diary study of participants‟ daily usage of ...
