5 Nov 2003 | | Subject: | hep-th | | Affiliation: | Department of Physics, University of Ljubljana and Primorska Institute for Natural Sciences and Technology) and H. B. Nielsen (Department of Physics, Niels Bohr Institute | | Abstract: | The genuine Kaluza-Klein-like theories (with no fields in addition to gravity with torsion) have difficulties with the existence of massless spinors after the compactification of some of dimensions of spacecite{witten}. We demonstrate in this letter on an example of a flat torus - as a compactified part of an (1+5)-dimensional space - that for constant fields and appropriate boundary conditions there exists in the 1+3 dimensional space a massless solution, which is mass protected and chirally coupled with a Kaluza-Klein charge to the corresponding gauge field. | | Source: | arXiv, hep-th/0311037 | | Services: | Forum | Review | PDF | Favorites | |
