New Strings for Old Veneziano Amplitudes I.Analytical Treatment

The bosonic string theory evolved as an attempt to find physical/quantum mechanical model capable of reproducing Euler's beta function (Veneziano amplitude) and its multidimensional analogue. The multidimensional analogue of beta function was studied mathematically for some time from different angles by mathematicians such as Selberg, Weil and Deligne among many others. The results of their studies apparently were not taken into account in physics literature on string theory. In recent publication hep-th/0212189 [IJMPA 19 (2004) 1655] an attempt was made to restore the missing links. The results of this publication are incomplete, however, since no attempts were made at reproducing known spectra of both open and closed bosonic string or at restoration of the underlying model(s) reproducing such spectra. Nevertheless, discussed in this publication the existing mathematical interpretation of the multidimensional analogue of Euler's beta function as one of the periods associated with the corresponding differential form "living" on the Fermat-type (hyper)surfaces, happens to be crucial for restoration of the quantum/statistical mechanical model reproducing such generalized beta function. Unlike the traditional formulations, this new model is supersymmetric. Although details leading to the restoration of this model are already presented in hep-th/0312294, the present work is aimed at more focused exposition of some of earlier presented results and is restricted mainly to the description of analytical properties of the Veneziano and Veneziano-like amplitudes. As such, it constututes Part I of our four parts work. Parts 2-4 will be devoted respectively to the group-theoretic, symplectic and combinatorial treatments of this new string-like supersymmetric model
