Spontaneous branes formation

This paper presents a study of brane formation in six-dimensional space. There is no a priori assumption of the brane(s) existence. However, the analysis of the generalized Einstein equations reveals that there are a set of metrics describing two static branes even in the absence of matter fields. The trapping of massive particles on branes is a consequence of the metric structure, which prevents these particles from moving between branes. It is shown that the communication between charged particles located on different branes provides by photons. Such positron-electron annihilation could be experimentaly study at the LHC collider. The Higgs field is distributed between the branes in such a way that it can serve as a Higgs portal connecting two worlds located on different branes. The values of the 4D physical parameters depend on the extra metric structure near the branes. A particular metric of the extra space was found to provide the observed value of the Higgs vacuum average. We also found a non-trivial effect of decompactification of the extra space when the Hubble parameter is varied.
