To explain the matter-antimatter asymmetry in the Zee–Babu (ZB) model, the sphaleron process in the baryogenesis scenario is calculated. It always satisfies the de-coupling condition and the strength of phase transition (S) is always greater than 1 in the presence of triggers other than that in the Standard Model, which are singly ($$h^{\pm }$$ h ± ) and doubly ($$k^{\pm \pm }$$ k ± ± ) charged scalar bosons. Sphaleron energies are in the range of 5-10 TeV, in calculation with bubble profiles containing free parameters and assuming nuclear bubbles of $$h^{\pm }$$ h ± and $$k^{\pm \pm }$$ k ± ± are very small. We tested the scaling law of sphaleron again with an average error of $$10\%$$ 10 % . When the temperature is close to the critical one ($$T_c$$ T c ), the density of nuclear bubble is produced very large and decreases as the temperature decreases. The key parameter is $$\alpha $$ α which results in the gravitational wave density parameter ($$\Omega h^2$$ Ω h 2 ) in the range of $$10^{-14}$$ 10 - 14 to $$10^{-12}$$ 10 - 12 when $$\beta /H^*=22.5$$ β / H ∗ = 22.5 , this is not enough to detect gravitational waves from electroweak phase transition (EWPT) according to the present LISA data but may be detected in the future. As the larger strength of phase transition is, the more $$\alpha $$ α increases (this increase is almost linear with S), the larger the gravitational wave density parameter is. Also in the context of considering the generation of gravitational waves, in the ZB model we calculated $$\alpha \sim \text {a few} \times 10^{-2}\ll 1$$ α ∼ a few × 10 - 2 ≪ 1 , so rigorously conclude that the EWPT is not strong even though $$S>1$$ S > 1 . We also suggest that, for a model with a lot of extra scalar particles and particles which play a role in mass generation, the stronger the EWPT process and the larger $$\Omega h^2$$ Ω h 2 can be.

The electroweak phase transition (EWPT) is considered in the framework of 3-3-1-1 model for Dark Matter. The phase structure within three or two periods is approximated for the theory with many vacuum expectation values (VEVs) at TeV and Electroweak scales. In the mentioned model, there are two pictures. The first picture containing two periods of EWPT, has a transition SU (3) → SU (2) at 6 TeV scale and another is SU (2) → U (1) transition which is the like-standard model EWPT. The second picture is an EWPT structure containing three periods, in which two first periods are similar to those of the first picture and another one is the symmetry breaking process of U (1) N subgroup. Our study leads to the conclusion that EWPTs are the first order phase transitions when new bosons are triggers and their masses are within range of some TeVs. Especially, in two pictures, the maximum strength of the SU (2) → U (1) phase transition is equal to 2.12 so this EWPT is not strong. Moreover, neutral fermions, which are candidates for Dark a vqphong@hcmus.edu.vn b nttuong.phys@gmail.com Matter and obey the Fermi-Dirac distribution, can be a negative trigger for EWPT. However, they do not make lose the first-order EWPT at TeV scale. Furthermore, in order to be the strong first-order EWPT at TeV scale, the symmetry breaking processes must produce more bosons than fermions or the mass of bosons must be much larger than that of fermions.

Doubly charged Higgs boson production at hadron colliders II: a Zee-Babu case study

Motivated by searches for so-called leptonic scalars at the LHC and the recent measurement of the W boson’s mass at the Tevatron, we revisit the phenomenology of the Zee-Babu model for neutrino masses and the ability to differentiate it from the Type II Seesaw model at the LHC. We conclude that this task is much more difficult than previously believed. All inputs equal in the two scenarios, we find that total and differential rates for producing pairs of doubly and singly charged scalars are identical in shape and only differ in normalization. The normalization is given by the ratio of hadronic cross sections and can be unity. Differences in cross sections are small and can be hidden by unknown branching rates. This holds for Drell-Yan, γγ fusion, and gg fusion, as well as observables at LO and NLO in QCD. This likeness allows us to reinterpret Run II limits on the Type II Seesaw and estimate projections for the HL-LHC. Using updated neutrino oscillation data, we also find that some collider observables, e.g., lepton flavor-violating branching ratios, are now sufficiently precise to provide a path forward. Other means of discrimination are also discussed. As a byproduct of this work, we report the availability of new Universal FeynRules Object libraries, the SM_ZeeBabu UFO, that enable fully differential simulations up to NLO+LL(PS) with tool chains employing MadGraph5_aMC@NLO.
