| Abstract: | A previously proposed algebra of asymptotic fields in quantum electrodynamics is formulated as a net of algebras localized
in regions which in general have unbounded spacelike extension. Electromagnetic fields may be localized in ‘symmetrical spacelike
cones’, but there are strong indications this is not possible in the present model for charged fields, which have tails extending
in all space directions. Nevertheless, products of appropriately ‘dressed’ fermion fields (with compensating charges) yield
bi-localized observables. |
