Field localization on 2-dim extra space is considered in the framework of f(R) gravity. It is shown that an interference of local matter energy distribution and a metric of the extra space form a point-like defect - 4-dim brane. The…

We consider phenomenological consequences of RS2-n model with infinite extra dimension, namely, the production, in high energy collisions, of a photon or Z-boson escaping from our brane in association with a photon remaining on the brane.…

The standard picture of viable higher-dimensional theories is that extra dimensions manifest themselves at short distances only, their effects being negligible at scales larger than some critical value. We show that this is not necessarily…
