Particle creation via relaxing hypermagnetic knots
نویسنده
چکیده
We demonstrate that particle production for fermions coupled chirally to an Abelian gauge field like the hypercharge field is provided by the microscopic mechanism of level crossing. For this purpose we use recent results on zero modes of Dirac operators for a class of localized hypermagnetic knots. ∗)email address: [email protected], [email protected] ∗∗)email address: [email protected] ∗∗∗)email address: [email protected]

Magnetogenesis : what we know and what we would like to know
Problems and perspectives concerning the existence of large-scale magnetic fields are described. Heeding observations, possible origins and implications of magnetic fields in spiral galaxies and in regular clusters are scrutinized in different cosmological frameworks including scenarios where conformal invariance is broken because of the evolution of the gauge couplings. The generation of the B...
متن کاملBaryon asymmetry from hypermagnetic helicity in dilaton hypercharge electromagnetism
Abstract The generation of the baryon asymmetry of the Universe (BAU) from the hypermagnetic helicity, the physical interpretation of which is given in terms of hypermagnetic knots, is studied in inflationary cosmology, taking into account the breaking of the conformal invariance of hypercharge electromagnetic fields through both a coupling with the dilaton and that with a pseudoscalar field. I...

The high-temperature plasma above the electroweak scale ;100 GeV may have contained a primordial hypercharge magnetic field whose anomalous coupling to the fermions induces a transformation of the hypermagnetic energy density into fermionic number. In order to describe this process, we generalize the ordinary magnetohydrodynamical equations to the anomalous case. We show that a not completely h...

متن کاملHypermagnetic Knots, Chern-Simons Waves and the Baryon Asymmetry
In a globally neutral plasma, the transversality of the magnetic fields implies, at high conductivity, the conservation of both magnetic flux and magnetic helicity. The plasma element evolves always glued together with magnetic flux lines whose number of associated knots and twists does not change . The energetical and the topological properties of the magnetic flux lines are conserved in the s...
