Proton β decay in large magnetic fields
Abstract
Both electromagnetic and strong interactions contribute to make, in magnetic fields of the order of B > 1014 T, the neutron stable against beta decay and for somewhat larger fields the proton becomes unstable to a decay into a neutron via β emission. Changes in chiral condensates due to such fields and an unexpectedly large field dependence of hadronic magnetic moments would modify these arguments. Fields of such magnitude may exist in colliding neutron stars and in the vicinity of cosmic strings. Possible astrophysical consequences are discussed. © 1993.
