The Effective Field Theory of Codimension-two Branes
Distributional sources of matter on codimension-two and higher branes are only well-defined as regularized objects. Nevertheless, intuition from effective field theory suggests that the low-energy physics on such branes should be independent of any high-energy regularization scheme. In this paper, we address this issue in the context of a scalar field model where matter fields (the standard mod...

متن کاملCodimension Two Branes and Distributional Curvature
In general relativity, there is a well-developed formalism for working with the approximation that a gravitational source is concentrated on a shell, or codimension one surface. By contrast, there are obstacles to concentrating sources on surfaces that have a higher co-dimension, for example, a string in a spacetime with dimension greater than or equal to four. Here it is shown that, by giving ...
متن کاملString Creation, D-branes and Effective Field Theory
This paper addresses several unsettled issues associated with string creation in systems of orthogonal Dp-D(8 − p) branes. The interaction between the branes can be understood either from the closed string or open string picture. In the closed string picture it has been noted that the DBI action fails to capture an extra RR exchange between the branes. We demonstrate how this problem persists u...
متن کاملCan codimension - two branes solve the cosmological constant problem ?
It has been suggested that codimension-two braneworlds might naturally explain the vanishing of the 4D effective cosmological constant, due to the automatic relation between the deficit angle and the brane tension. To investigate whether this cancellation happens dynamically, and within the context of a realistic cosmology, we study a codimension-two braneworld with spherical extra dimensions c...
