A possible origin of superconducting currents in cosmic strings
Helder Chávez1 and Luis Masperi2,3
Show affiliationsThe scattering and capture of right-handed neutrinos by an Abelian cosmic string in the SO(10) grand unification model are considered. The scattering cross section of neutrinos per unit length due to the interaction with the gauge and Higgs fields of the string is much larger in its scaling regime than in the friction regime because of the larger infrared cutoff of the former. The probability of capture in a zero mode of the string accompanied by the emission of a gauge or Higgs boson shows a resonant peak for the neutrino momentum of the order of its mass. Due to the decrease in the number of strings per unit of comoving volume in the scaling epoch, the cosmological consequences of the superconducting strings formed in this regime will be much smaller than those which may already be produced in the friction regime; in particular as possible sources of ultraenergetic cosmic rays.
