Classical Renormalization of Codimension‐two Brane Couplings Available to Purchase

The curvature on codimension‐two and higher branes is not regular for arbitrary matter sources. Nevertheless, the low‐energy theory for an observer on such a brane should be well‐defined and independent to any regularization procedure. This is achieved via appropriate classical renormalization of the brane couplings, and leads to a natural hierarchy between standard model couplings and couplings to gravity.
