Abstrakt

In contrast to the usual representations of the PoincareŽ group of finite spin or helicity the Wigner representations of mass zero and infinite spin are known to be incompatible with point-like localized quantum fields. We present here a construction of quantum fields associated with these representations that are localized in semi-infinite, space-like strings. The construction is based on concepts outside the realm of Lagrangian quantization with the potential for further applications. Œ 2004 Elsevier B.V. All rights reserved.
