Inverse seesaw and (g ? 2) anomalies in B ? L extended two Higgs doublet model

چکیده
We propose a gauged U(1)B?L extended two Higgs doublet model to explain both neutrino mass and lepton anomalous magnetic moments (g?2). Neutrino is generated via an inverse seesaw mechanism by introducing singlet fermions. Especially, we update the result of muon (g?2) in light very recent report E989 experiment at Fermilab, indicating a?FNAL=116592040(54)×10?11. Combining BNL result, have following deviation from standard prediction ?a?=(2.51±5.9)×10?10 4.2 ?.

The B → X d l + l − decay in general two Higgs doublet model
The branching ratio, forward–backward asymmetry and CP violating asymmetry for B → Xd l+l− decay, in framework of the general two Higgs doublet model, with extra phase angle in the charged–Higgs–fermion coupling, are calculated. It is shown that studying the CP violating asymmetry is an efficient tool for establishing new
متن کاملDecay in Two Higgs Doublet Model
The rare K + → π + ν ¯ ν decay is investigated in the context of type II two-Higgs-doublet model (2HDM). By using the existing experimental data of the branching ratio, restrictions on the free parameters of the model m H , and tanβ are obtained: 0.7 ≤ tanβ ≤ 0.8, and 500GeV ≤ m H ≤ 700GeV .
متن کامل2 Phenomenological analysis of the Two Higgs Doublet Model
The Two Higgs Doublet model and its phenomenological implications are discussed. A brief survey on the present status of this model is given. In particular, we concentrate on the Two Higgs Doublet Model with Flavor Changing Neutral Currents. First, we develop some new parametrizations of the 2HDM type III, in such a way that the relation of it with models type I and type II become apparent, bas...
