CP Violating Bubble Wall Profiles
S. J. Huber, P. John, M. Laine +1
We solve the equations of motion for a CP violating phase between the two Higgs doublets at the bubble wall of the MSSM electroweak phase transition. Contrary to earlier suggestion…
Low Energy Constants from Kl4 Form-Factors
G. Amorós, J. Bijnens, P. Talavera
We have calculated the form-factors F and G in K ---> pi pi e nu decays (Kl4) to two-loop order in Chiral Perturbation Theory (ChPT). Combining this together with earlier two-loop…
Physical origin of "chaoticity" of neutrino asymmetry
Antti Sorri
We consider the indeterminacy in the sign of the neutrino asymmetry generated by active-sterile neutrino oscillations in the early universe. The dynamics of asymmetry growth is dis…
A remark on sphaleron erasure of baryon asymmetry
M. Laine, M. Shaposhnikov
We complete an existing result for how the baryon asymmetry left over after a period of full thermal equilibrium depends on different lepton asymmetries.
Quantum Magnetic Collapse
M. Chaichian, S. S. Masood, C. Montonen +2
We study the thermodynamics of degenerate electron and charged vector boson gases in very intense magnetic fields. In degenerate conditions of the electron gas, the pressure transv…
Search for CP Violation at a Neutrino Factory in a Four-Neutrino Model
Anna Kalliomäki, Jukka Maalampi, Morimitsu Tanimoto
The CP violation effects in long baseline neutrino oscillations are studied in the framework of a four-neutrino model (three active neutrinos and one sterile neutrino). It is assum…
