Hi Arituay,

Welcome to the BAUT forum.

I don't think you can say that String/M/Brane theory being correct says that it is certain that gravity leaks from brane to brane. There are many such models, and not all agree about visible multi-dimensional consequences.

I personally don't have links to papers on this, but since there is no shortage, I'm sure someone on the forum will drop by with some pointers soon.
