Magnetic field and curvature effects on pair production. II. Vectors and implications for chromodynamics
Abstract
We calculate the pair production rates for spin-1 or vector particles on spaces of the form M ×R1 ,1 , with M corresponding to R2 (flat), S2 (positive curvature), and H2 (negative curvature), with and without a background (chromo)magnetic field on M . Beyond highlighting the effects of curvature and background magnetic field, this is particularly interesting since vector particles are known to suffer from the Nielsen-Olesen instability, which can dramatically increase pair production rates. The form of this instability for S2 and H2 is obtained. We also give a brief discussion of how our results relate to ideas about confinement in non-Abelian theories.
