Title: The minimal fermionic model of electroweak baryogenesis

Abstract

We present the minimal model of electroweak baryogenesis induced by fermions. The model consists of an extension of the Standard Model with one electroweak singlet fermion and one pair of vector like doublet fermions with renormalizable couplings to the Higgs. A strong first order phase transition is radiatively induced by the singlet-doublet fermions, while the origin of the baryon asymmetry is due to asymmetric reflection of the same set of fermions on the expanding electroweak bubble wall. The singlet-doublet fermions are stabilized at the electroweak scale by chiral symmetries and the Higgs potential is stabilized by threshold corrections coming from a multi-TeV ultraviolet completion which does not play any significant role in the phase transition. We work in terms of background symmetry invariants and perform an analytic semiclassical calculation of the baryon asymmetry, showing that the model may effectively generate the observed baryon asymmetry for percent level values of the unique invariant CP violating phase of the singlet-doublet sector. We include a detailed study of electron electric dipole moment and electroweak precision limits, and for one typical benchmark scenario, we also recast existing collider constraints, showing that the model is consistent with all current experimental data. We point out thatmore »« less

We point out that fermion induced electroweak baryogenesis has irreducible phenomenology at the 13 TeV LHC since the new fermions must be at the electroweak scale, have electroweak quantum numbers and couple strongly to the Higgs. The most promising searches involve topologies with multiple leptons and missing energy in the final state.},

Anatomy of the electroweak phase transition for dark sector induced baryogenesis

Journal Article Carena, Marcela ; Li, Ying-Ying ; Ou, Tong ; ... - Journal of High Energy Physics (Online)

We investigate the electroweak phase transition patterns for a recently proposed baryogenesis model with CP violation originated in the dark sector. The model includes a complex scalar singlet-Higgs boson portal, a U(1)_l gauge lepton symmetry with a Z' gauge boson portal and a fermionic dark matter particle. We find a novel thermal history of the scalar sector, featuring a Z₂ breaking singlet vacuum in the early Universe driven by a dark Yukawa coupling, that induces a one-step strongly first order electroweak phase transition. We explore the parameter space that generates the observed matter-antimatter asymmetry and dark matter relic abundance, whilemore »« less

Electroweak-like baryogenesis with new chiral matter

Journal Article Fujikura, Kohei ; Harigaya, Keisuke ; Nakai, Yuichiro ; ... - Journal of High Energy Physics (Online)

We propose a framework where a phase transition associated with a gauge symmetry breaking that occurs (not far) above the electroweak scale sets a stage for baryogenesis similar to the electroweak baryogenesis in the Standard Model. A concrete realization utilizes the breaking of SU(2)_R × U(1)_X → U(1)_Y. New chiral fermions charged under the extended gauge symmetry have nonzero lepton numbers, which makes the B - L symmetry anomalous. The new lepton sector contains a large flavor-dependent CP violation, similar to the Cabibbo-Kobayashi-Maskawa phase, without inducing sizable electric dipole moments of the Standard Model particles.

Dark $C P$ violation and gauged lepton or baryon number for electroweak baryogenesis

Journal Article Carena, Marcela ; Quirós, Mariano ; Zhang, Yue - Physical Review. D.

We explore the generation of the baryon asymmetry in an extension of the standard model where the lepton number is promoted to a U(1)ℓ gauge symmetry with an associated Z' gauge boson. This is based on a novel electroweak baryogenesis mechanism first proposed by us in Ref. Extra fermionic degrees of freedom, including a fermionic dark matter χ, are introduced in the dark sector for anomaly cancellation. The lepton number is spontaneously broken at high scale and the effective theory, containing the standard model, the Z', the fermionic dark matter, and an additional complex scalar field S, violates CP inmore »« less

Electroweak baryogenesis in supersymmetric models

Journal Article Huet, P ; Nelson, A E - Physical Review, D

The baryon density which may be produced during the electroweak phase transition in supersymmetric models is computed, taking into account the previously neglected effects of transport, strong and weak anomalous fermion number violation, thermal scattering, and a new method for computing {ital CP}-violating processes during the transition. We can account for the observed baryon asymmetry, provided new {ital CP}-violating phases are greater than {approximately}10{sup {minus}2}{endash}10{sup {minus}4}, and some superpartners are light enough to be relevant during the transition, which takes place at a temperature of 50{endash}100 GeV. In one case, the light superpartners are the top squarks and the charginosmore »« less

Electroweak baryogenesis in non-minimal composite Higgs models

Journal Article Espinosa, José R. ; Gripaios, Ben ; Konstandin, Thomas ; ... - Journal of Cosmology and Astroparticle Physics

We address electroweak baryogenesis in the context of composite Higgs models, pointing out that modifications to the Higgs and top quark sectors can play an important rôle in generating the baryon asymmetry. Our main observation is that composite Higgs models that include a light, gauge singlet scalar in the spectrum [as in the model based on the symmetry breaking pattern SO(6) → SO(5)], provide all necessary ingredients for viable baryogenesis. In particular, the singlet leads to a strongly first-order electroweak phase transition and introduces new sources of CP violation in dimension-five operators involving the top quark. We discuss the amountmore »« less
