Freeze-in and freeze-out generation of lepton asymmetries after baryogenesis in the MSM
Shintaro Eijima, Mikhail Shaposhnikov, Inar Timiryasov
The MSM -- an extension of the Standard Model by three relatively light singlet Majorana fermions -- allows for the generation of lepton asymmetry which is several o…
Baryon Asymmetry of the Universe without Boltzmann or Kadanoff-Baym
J. -S. Gagnon, M. Shaposhnikov
We present a formalism that allows the computation of the baryon asymmetry of the universe from first principles of statistical physics and quantum field theory that is applicable…
Effective gauge theories on domain walls via bulk confinement?
M. Laine, H. B. Meyer, K. Rummukainen +1
We study with lattice techniques the localisation of gauge fields on domain wall defects in 2+1 dimensions, following a scenario originally proposed by Dvali and Shifman for 3+1 di…
Localisation and mass generation for non-Abelian gauge fields
M. Laine, H. B. Meyer, K. Rummukainen +1
It has been suggested recently that in the presence of suitably "warped" extra dimensions, the low-energy limit of pure gauge field theory may contain massive elementary vector bos…
Primordial magnetic fields from inflation???
Massimo Giovannini, Mikhail Shaposhnikov
In this note we argue that the breaking of conformal invariance because of the coupling of a charged scalar field to gravity is not sufficient for the production of seed galactic m…
Primordial magnetic fields from inflation?
M. Giovannini, M. Shaposhnikov
The hot plasma above the electroweak scale contains (hyper) charged scalar particles which are coupled to Abelian gauge fields. Scalars may interact with gravity in a non-conformal…
