Universal Seesaw Leptogenesis
K. S. Babu, Maximilian Berbig, Srubabati Goswami +1
We study the implications for leptogenesis in a class of left-right symmetric model, where all fermion masses are induced through the Universal Seesaw mechanism. Unlike conventiona…
Type II Seesaw Leptogenesis in a Majoron background
Maximilian Berbig
We discuss spontaneous Leptogenesis in the Type II Seesaw model of neutrino masses featuring an electroweak triplet scalar in a coherent pseudo Nambu-Goldstone boson (pNGB) bac…
About electroweak domain walls in Majoron models
Maximilian Berbig
Some time ago it was claimed in "Spontaneous Breaking of Lepton Number and Cosmological Domain Wall Problem" (Phys. Rev. Lett. 122, 151301 (2019)) that non perturbative instantons…
Kick it like DESI: PNGB quintessence with a dynamically generated initial velocity
Maximilian Berbig
Motivated by the hint for time-dependent dynamical dark energy from an analysis of the DESI Baryon Accoustic Oscillation (BAO) data together with information from the Cosmic Microw…
Minimal solution to the axion isocurvature problem from a nonminimal coupling
Maximilian Berbig
The main limitation for preinflationary breaking of Peccei-Quinn (PQ) symmetry is the upper bound on the Hubble rate during inflation from axion isocurvature fluctuations. This lea…
Dynamical origin of neutrino masses and dark matter from a new confining sector
Maximilian Berbig, Juan Herrero-Garcia, Giacomo Landini
A dynamical mechanism, based on a confining non-abelian dark symmetry, which generates Majorana masses for hypercharge-less fermions, is proposed. We apply it to the inverse seesaw…
Diraxiogenesis
Maximilian Berbig
The family of Dirac Seesaw models offers an intriguing alternative explanation for the smallness of neutrino masses without necessarily requiring microscopic lepton number violatio…
Impact of high-scale Seesaw and Leptogenesis on inflationary tensor perturbations as detectable gravitational waves
Maximilian Berbig, Anish Ghoshal
We discuss the damping of inflationary gravitational waves (GW) that re-enter the horizon before or during an epoch, where the energy budget of the universe is dominated by an unst…
The Type II Dirac Seesaw Portal to the mirror sector: Connecting neutrino masses and a solution to the strong CP problem
Maximilian Berbig
We present a version of the Type II Seesaw mechanism for parametrically small Dirac neutrino masses. Our model starts from an $\text{SU}(2)_\text{L} \otimes \text{SU}(2)'\otimes \t…
S.M.A.S.H.E.D.: Standard Model Axion Seesaw Higgs Inflation Extended for Dirac Neutrinos
Maximilian Berbig
Inspired by the S.M.A.S.H. framework we construct a model that addresses the strong CP problem, axion dark matter, inflation and Dirac neutrino masses as well as leptogenesis. The…
Freeze-In of radiative keV-scale neutrino dark matter from a new
Maximilian Berbig
We extend the Dirac Scotogenic model with the aim of realizing neutrino masses together with the mass of a keV-scale dark matter (DM) candidate via the same one-loop topology. Two…
The Hubble tension and a renormalizable model of gauged neutrino self-interactions
Maximilian Berbig, Sudip Jana, Andreas Trautner
We present a simple extension of the Standard Model that leads to renormalizable long-range vector-mediated neutrino self-interactions. This model can resolve the Hubble tension by…
