Primordial magnetic fields, anomalous isocurvature fluctuations and Big Bang nucleosynthesis
We show that the presence of primordial stochastic (hypercharge) magnetic fields before the electroweak (EW) phase transition induces isocurvature fluctuations (baryon number inhomogeneities). Depending on the details of the magnetic field spectrum and on the particle physics parameters (such as the...
