Title: CP violating effects in heavy neutrino oscillations: implications for colliders and leptogenesis

Abstract

Two of the important implications of the seesaw mechanism are: (i) a simple way to understand the small neutrino masses, and (ii) the origin of matter-anti-matter asymmetry in the universe via the leptogenesis mechanism. For TeV-scale seesaw models, successful leptogenesis requires that the right-handed neutrinos (RHNs) must be quasidegenerate and if they have CP violating phases, they also contribute to the CP asymmetry. We investigate this in the TeV-scale left-right models for seesaw and point out a way to probe the quasi-degeneracy possibility with CP violating mixings for RHNs in hadron colliders using simple observables constructed out of same-sign dilepton charge asymmetry (SSCA). In particular, we isolate the parameter regions of the model, where the viability of leptogenesis can be tested using the SSCA at the Large Hadron Collider, as well as future 27 TeV and 100 TeV hadron colliders. We also independently confirm an earlier result that there is a generic lower bound on the WR mass of about 10 TeV for leptogenesis to work.

Probing resonant leptogenesis at the LHC

Journal Article Blanchet, Steve ; Chacko, Z ; Granor, Solomon S ; ... - Physical Review. D, Particles Fields

We explore direct collider probes of the resonant leptogenesis mechanism for the origin of matter. We work in the context of theories where the standard model (SM) is extended to include an additional gauged U(1) symmetry broken at the TeV scale, and where the light neutrinos obtain mass through a type I seesaw at this scale. The CP asymmetry that generates the observed matter-antimatter asymmetry manifests itself in a difference between the number of positive and negative like-sign dileptons N(l{sup +}l{sup +})-N(l{sup -}l{sup -}) that arise in the decay of the new Z{sup '} gauge boson to two right-handed neutrinosmore »« less

Scalar triplet flavored leptogenesis: a systematic approach

Journal Article Sierra, D. Aristizabal ; Dhen, Mikaël ; Hambye, Thomas - Journal of Cosmology and Astroparticle Physics

Type-II seesaw is a simple scenario in which Majorana neutrino masses are generated by the exchange of a heavy scalar electroweak triplet. When endowed with additional heavy fields, such as right-handed neutrinos or extra triplets, it also provides a compelling framework for baryogenesis via leptogenesis. We derive in this context the full network of Boltzmann equations for studying leptogenesis in the flavored regime. To this end we determine the relations which hold among the chemical potentials of the various particle species in the thermal bath. This takes into account the standard model Yukawa interactions of both leptons and quarks asmore »« less

Hot leptogenesis from thermal Dark Matter

Journal Article Bernal, Nicolas ; Fong, Chee Sheng - Journal of Cosmology and Astroparticle Physics

In this work, we investigate a scenario in which heavy Majorana Right-Handed Neutrinos (RHNs) are in thermal equilibrium with a dark sector with temperature higher than the Standard Model (SM) thermal bath. Specifically, we consider the scenario in which thermal Dark Matter (DM) abundance is fixed from the freeze-out of DM annihilations into RHNs. Due to the inert nature of the RHNs, we show that it is possible for the two sectors to remain thermally decoupled by having more than two generations of the RHNs. The hotter temperature implies higher abundances of DM and RHNs with the following consequences. Formore »« less

Leptogenesis in Higgs triplet model

Journal Article Scopel, Stefano - AIP Conference Proceedings

We analyze leptogenesis in a supersymmetric triplet seesaw scenario that explains at the same time the baryon asymmetry in the Universe and the observed neutrino masses. First, we adopt a phenomenolog approach where, in order to single out the main features of the model, the decay branching ratios of the triplets and the amount of CP-violation in their different decay channels are assumed as free parameters. We then consider the particular example of soft leptogenesis, which employs a non-vanishing phase and a resonant behavior in the supersymmetry breaking sector to generate CP violation. In both scenarios we solve the relevantmore »« less

Radiatively induced leptogenesis in a minimal seesaw model

Journal Article Felipe, R Gonzalez ; Joaquim, F R ; Nobre, B M - Physical Review. D, Particles Fields

We study the possibility that the baryon asymmetry of the Universe is generated in a minimal seesaw scenario where two right-handed Majorana neutrinos with degenerate masses are added to the standard model particle content. In the usual framework of thermal leptogenesis, a nonzero CP asymmetry can be obtained through the mass splitting induced by the running of the heavy Majorana neutrino masses from their degeneracy scale down to the seesaw scale. Although, in the light of the present neutrino oscillation data, the produced baryon asymmetry turns out to be smaller than the experimental value, the present mechanism could be viablemore »« less
