Research Abstract

We have developed a quantum mechanical formulation of the string field theory, which is a natural candidate framework of the string unifying every elementary particles and space-time. This enables us to study properties of various quantum processes and also to give a basis toward the development of non-perturbative methods. We also have given a way to avoid known problem in the conventional method.
