# String-localized quantum fields from Wigner representations

February 16, 2004

In contrast to the usual representations of of the PoincarĂ© group of finite
spin or helicity the Wigner representations of mass zero and infinite spin are
known to be incompatible with pointlike 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.
