We study the collision of a brane with a black hole. Our aim is to explore the topology changing process of perforation of a brane. The brane is described as a field theoretical domain wall in the context of an axion-like model consisting of a complex scalar effective field theory with approximate U (1) symmetry. We simulate numerically the dynamics of the collision and illustrate the transition from the configuration without a hole to the pierced one with the aid of a phase diagram. The process of perforation is found to depend on the collisional velocity, and, contrary to our expectation, we observe that above a critical value of the velocity, the black hole has no chance to perforate the wall. That is: high energy collisions do not assist piercing. We also show that, only when the model parameters are fine-tuned so that the energy scale of the string is very close to that of the domain wall, the collision of the wall with the black hole has a possibility to provide a mechanism to erase domain walls, if the hole expands. However, in such cases, domain walls will form with many holes edged by a string and therefore disappear eventually. Therefore this mechanism is unlikely to be a solution to the cosmological domain wall problem, although it may cause some minor effects on the evolution of a domain wall network.

“…3-branes in relevant previous works are constructed by the classical solutions in gauge theory; such as kink in five dimensions (5D), Abelian-Higgs vortex in 6D, and t'Hooft-Polyakov monopole in 7D [24,25,26,27,28].…”

Localizing gravity on Maxwell gaugedCP1model in six dimensions

We shall consider about a 3-brane embedded in six-dimensional space-time with a negative bulk cosmological constant. The 3-brane is constructed by a topological soliton solution living in two-dimensional axially symmetric transverse subspace. Similar to most previous works of sixdimensional soliton models, our Maxwell gauged CP 1 brane model can also achieve to localize gravity around the 3-brane. The CP 1 field is described by a scalar doublet and derived from O(3) sigma model by projecting it onto two-dimensional complex space. In that sense, our framework is more effective than other solitonic brane models concerning with gauge theory. We shall also discuss about linear stability analysis for our new model by fluctuating all fields.

“…It has been shown [11] that a collision of a kink with a boundary generically leads to a transition between a vacuum state (11) with a single-charged three-brane and a vacuum state (10) without a three-brane. Topological transitions on the M-theory side can, therefore, be modelled by simple scalar field dynamics using the action (7).…”

“…However, these processes can be studied in the context of a toy model where the three-branes are replaced by smooth kink solutions of a bulk scalar field theory. The following action [11] for this toy model, replacing the M-theory action (1),…”
