Resonant electromagnetic leptogenesis with coherent heavy-neutrino evolution
Rin Takada
We study TeV-scale electromagnetic leptogenesis generated by the gauge-invariant neutrino-dipole operators and . The benchmark Wilson coefficients are specified at…
Long-wavelength amplification of an NLS conserved-charge violation in a one-dimensional Gross-Pitaevskii-Poisson field
Rin Takada
Can weak self-gravity be treated as a small, generic perturbation of the integrable one-dimensional cubic nonlinear Schrödinger equation? We test this question by following the fi…
Yukawa-assisted charged-lepton dipoles in resonant electromagnetic leptogenesis
Rin Takada
We study the charged-lepton dipole contribution that is linear in the neutrino-dipole coefficients and in the renormalizable neutrino Yukawa matrix . We consider…
Electromagnetic Leptogenesis -- an EFT-Consistent Analysis via Wilson Coefficients. Part II. Low-Scale, Resonant Regime
Rin Takada
We study electromagnetic leptogenesis (EMLG) in the low-scale, resonant regime within a fully effective-field-theory (EFT)--consistent framework. Starting from a UV Lagrangian and…
Electromagnetic Leptogenesis -- an EFT-Consistent Analysis via Wilson Coefficients. Part I. Low-Scale, Non-Resonant Regime
Rin Takada
We analyse electromagnetic leptogenesis within the framework of an effective field theory, where the dynamics is governed by the gauge-invariant dipole operator . The Wilso…
Leptogenesis in the presence of density perturbations
Kenta Hotokezaka, Ryusuke Jinno, Rin Takada
We point out a new effect on the freeze-out process of heavy particles induced by density perturbations in the early universe, which we call ``acoustically driven freeze-out.'' Thi…
