![]() ![]() The task became more difficult as the chiral characteristic does not survive the compactification process rendering the theory inconsistent with the real world. Compactification - The remaining six extra dimensions have to be reduced further to small size.If the N = 1 version of the super generator is selected, then it seems to incorporate the chiral character of the fermions nicely as well (see Table 02). Thus, the 26 dimensional space for the bosons has to be compacted preliminarily to ten extra dimensions by rolling up 16 to tiny circles or set to zero. It requires a ten dimensional space time to eliminate the anomlies, inconsistencies, techyons, etc. Supersymmetry - Supersymmetry is used to add fermions into the bosonic string theory.The remaining problems of tachyon and missing fermions can be resolved only by adding supersymmetry into the theory. This theory is plagued with a lot of problems, parts of which can be eliminated by going to a space of 26 dimensions. String - The initial theory of the bosonic string corresponds in low energy limit to particles with integer spin, i.e., they are all bosons.Followings are a brief description of the steps leading to this unique selection, and its other special properties beneficial to the development of the Superstring theory.įigure 22 Connection 1 to Calabi-Yau Manifold The connection between string theory and Calabi-Yau manifold is mainly through supersymetry (Figure 22), although there are other linkages that make it even more desirable. ![]()
