Spherically Symmetric Thick Branes in Vacuum
نویسندگان
چکیده
We consider a spherical thick 3-brane immersed in a five-dimensional bulk spacetime. We demonstrate how the thick brane equation of motion expanded in powers of the thickness of the brane can be obtained from the expected junction conditions on the boundaries of thick brane with the two embedding spacetimes. It is shown that the finite thickness leads to a faster collapse of the spherical shell. E-mail address: [email protected] E-mail address: [email protected] E-mail address: [email protected] 1

Multidimensional Cosmological and Spherically Symmetric Solutions with Intersecting p-branes
Multidimensional model describing the cosmological evolution and/ or spherically symmetric configuration with (n+1) Einstein spaces in the theory with several scalar fields and forms is considered. When electro-magnetic composite p-brane ansatz is adopted, n ”internal” spaces are Ricci-flat, one space M0 has a non-zero curvature, and all p-branes do not ”live” in M0, a class of exact solutions ...

متن کاملSpherically Symmetric Solutions in a New Braneworld Massive Gravity Theory
In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the five-dimensional bulk graviton is considered to be massive. The five dimensional nonlinear ghost-free massive gravity theory affects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical s...
متن کاملMost General Spherically Symmetric M2-branes and Type IIB Strings
We obtain the most general spherically symmetric M2-branes and type IIB strings, with R 1,2 × SO(8) and R 1,1 × SO(8) isometries, respectively. We find that there are 12 different classes of M2-branes, and we study their curvature properties. In particular, we obtain new smooth M2-brane wormholes that connect two asymptotic regions: one is flat and the other can be either flat or AdS 4 × S 7. W...
متن کاملHawking radiation of black p-branes via gauge and gravitational anomalies
We investigate the Hawking radiation of black p-branes in superstring theories through the method of anomaly cancelation proposed by Robinson andWilczec et al. The metrics of black p-branes are spherically symmetric, but not the Schwarzschild type generally. We find that in order to make the method of Robinson and Wilczec et al. effective for the calculation of Hawking fluxes for general non-Sc...
