B−L-symmetric Baryogenesis with Leptonic Quintessence
نویسنده
چکیده
We discuss a toy model where baryogenesis and cosmic acceleration are driven by a leptonic quintessence field coupled to the standard model sector via a massive mediating scalar field. It does not require the introduction of B−L-violating interactions below the inflationary scale. Instead, a B−L-asymmetry is stored in the quintessence field, which compensates for the corresponding observed baryon asymmetry. PACS numbers: 11.30.Fs, 98.80.Cq, 95.36.+x

Leptonic Dark Energy and Baryogenesis
We consider a baryogenesis scenario, where the difference of baryon (B) and lepton (L) number is conserved in such a way that the B−L asymmetry in the standard model sector is compensated by an asymmetry of opposite sign stored in the dark energy sector. Therefore, we introduce a toy-model in which a complex quintessence field carries a B−L asymmetry at late times. We determine the produced bar...
متن کاملQuintessence, inflation and baryogenesis from a single pseudo-Nambu-Goldstone boson
We exhibit a model in which a single pseudo-Nambu-Goldstone boson explains dark energy, inflation and baryogenesis. The model predicts correlated signals in future collider experiments, WIMP searches, proton decay experiments, dark energy probes, and the PLANCK satellite CMB measurements.

In the standard model and most of its extensions the electroweak transition is too weak to affect the cosmological baryon asymmetry. Due to sphaleron processes baryogenesis in the high-temperature, symmetric phase of the standard model is closely related to neutrino properties. The experimental indications for very small neutrino masses from the solar and the atmospheric neutrino deficits favou...
متن کاملThe Νmsm, Leptonic Asymmetries, and Properties of Singlet Fermions
We study in detail the mechanism of baryon and lepton asymmetry generation in the framework of the νMSM (an extension of the Standard Model by three singlet fermions with masses smaller than the electroweak scale). We elucidate the issue of CP-violation in the model and define the phase relevant for baryogenesis. We clarify the question of quantum-mechanical coherence, essential for the lepton ...
متن کاملLow Scale Leptogenesis from Non-Leptonic CP -Phases
We point out new sources of CP -violation for leptogenesis at electroweak temperatures. In supersymmetric models, CP -violation leading to a lepton asymmetry can originate from the phase of the μ-term relative to soft gaugino masses or soft triscalar interactions. As an additional possibility, we consider a top-quark loop in a multiple Higgs doublet model. Leptogenesis from these non-leptonic C...
