Abstrakt

For any massless, irreducible representation of the covering of the proper, orthochronous Poincare group we construct covariant, free quantum fields that generate the representation space from the vacuum and are localized in semi-infinite strings in the sense of commutation or anti-commutation of the field operators at space-like separation of the strings. Besides the space-like string direction the field operators carry a spinor or tensor index for one of the finite dimensional representations D-(j/2,D- k/2) of SL( 2, C). For given (j, k) the possible integer or half-integer values that the helicity h can take are for string fields only restricted by the condition vertical bar h vertical bar
