Bosonic string theory with the possibility for an arbitrary number of strings\n- i.e. a string field theory - is formulated by a Hilbert space (a Fock space),\nwhich is just that for massless noninteracting scalars. We earlier presented\nthis novel type of string field theory, but now we show that it leads to\nscattering just given by the Veneziano model amplitude. Generalization to\nstrings with fermion modes would presumably be rather easy. It is\ncharacteristic for our formulation /model that: 1) We have thrown away some\nnull set of information compared to usual string field theory, 2)Formulated in\nterms of our objects" (= the non-interacting scalars) there is no interaction\nand essentially no time development(Heisenberg picture), 3) so that the\nS-matrix is in our Hilbert space given as the unit matrix, S=1, and 4) the\nVeneziano scattering amplitude appear as the overlap between the initial and\nthe final state described in terms of the objects". 5) The integration in the\nEuler beta function making up the Veneziano model appear from the summation\nover the number of objects" from one of the incoming strings which goes into a\ncertain one of the two outgoing strings. A correction from Weyl anomaly is\nneeded to get the correct form of the Veneziano amplitude and it only fits for\n26 dimensions.\n
