    Successful Supersymmetric Inflation by Ross, G, Sarkar, S

    Published 1995
    “…This is low enough to solve the gravitino problem but high enough to allow baryogenesis after inflation. Such consistency requires that the generation of gravitational waves be negligible and that the spectrum of scalar density perturbations depart significantly from scale-invariance, thus improving the fit to large-scale structure in an universe dominated by cold dark matter. …”

    Resonant particle production in branonium by Rosa, J, March-Russell, J

    Published 2007
    “…We discuss the effects of transverse space compactification on the probe's motion, showing that it leads to the creation of angular momentum in a similar way to the Affleck-Dine mechanism for baryogenesis. Finally, we describe possible final states of the system and their potential relevance to cosmology.…”

    Dark matter and baryon-number generation in quintessential inflation via hierarchical right-handed neutrinos by Soichiro Hashiba, Jun'ichi Yokoyama

    Published 2019-11-01
    “…Incorporating three generations of right-handed Majorana neutrinos to quintessential inflation, we construct a model which simultaneously explains inflation, dark energy, dark matter and baryogenesis. These neutrinos have hierarchical masses M3∼1013GeV,M2∼1011GeV,M1∼10keV and are produced by gravitational particle production in the kination regime after inflation. …”

    Unitarity-safe models of non-minimal inflation in supergravity by Constantinos Pallis

    Published 2018-12-01
    “…Focusing, moreover, on a model employing a gauge non-singlet inflaton, we show that a solution to the $$\mu $$ μ problem of MSSM and baryogenesis via non-thermal leptogenesis can be also accommodated.…”

    Limits on quark nugget dark matter from cosmic ray detectors by Lawson Kyle

    Published 2015-01-01
    “…In particular I will describe a model in which the dark matter consists of heavy “nuggets” of quarks and antiquarks, and highlight its relation to baryogenesis. As this form of dark matter is based in known physics its properties, as established by arguments from nuclear physics and electrodynamics, are strongly constrained. …”

    Composite dynamics in the early Universe by Stefania De Curtis, Luigi Delle Rose, Giuliano Panico

    Published 2019-12-01
    “…A bonus of the Nambu-Goldstone boson nature of the scalar-sector dynamics is the presence of non-renormalisable Higgs in- teractions that can trigger additional sources of CP violation needed to realise baryogenesis at the electroweak scale. Another interesting aspect of this scenario is the generation of gravitational wave signatures that can be observed at future space-based interferometers.…”

    GeV-scale hot sterile neutrino oscillations: a numerical solution by J. Ghiglieri, M. Laine

    Published 2018-02-01
    “…Abstract The scenario of baryogenesis through GeV-scale sterile neutrino oscillations is governed by non-linear differential equations for the time evolution of a sterile neutrino density matrix and Standard Model lepton and baryon asymmetries. …”

    Chiral gravitational effect in time-dependent backgrounds by Kohei Kamada, Jun’ya Kume, Yusuke Yamada

    Published 2021-05-01
    “…We find that the non-trivial time dependence of chiral chemical potential, which can be induced in some scenarios of baryogenesis, is the key ingredient of the chiral gravitational effect. …”

    Matter–antimatter asymmetry induced by a running vacuum coupling by J. A. S. Lima, D. Singleton

    Published 2017-12-01
    “…Abstract We show that a CP-violating interaction induced by a derivative coupling between the running vacuum and a non-conserving baryon current may dynamically break CPT and trigger baryogenesis through an effective chemical potential. …”

    Neutrinoless double β decay and low scale leptogenesis by Marco Drewes, Shintaro Eijima

    Published 2016-12-01
    “…It has previously been claimed that the requirement for successful baryogenesis implies that the rate of neutrinoless double β decay in this scenario is always smaller than the standard prediction from light neutrino exchange alone. …”

    Electroweak phase transition in non-minimal Higgs sectors by Philipp Basler, Margarete Mühlleitner, Jonas Müller

    Published 2020-05-01
    “…Abstract Higgs sector extensions beyond the Standard Model (BSM) provide additional sources of CP violation and further scalar states that help to trigger a strong first order electroweak phase transition (SFOEWPT) required to generate the observed baryon asymmetry of the Universe through electroweak baryogenesis. We investigate the CP-violating 2-Higgs-Doublet Model (C2HDM) and the Next-to-Minimal 2-Higgs-Doublet Model (N2HDM) with respect to their potential to generate an SFOEWPT while being compatible with all relevant and recent theoretical and experimental constraints. …”

    Published 2023-08-01
