Mass spectrum of scalar and gauge fields in the cosmological multiply warped brane-world
A. S. Ribeiro, G. Alencar, R. R. Landim +1
In this paper, we compute the massive modes of scalar and gauge fields in a multiply warped brane-world scenario in six-dimensional spacetime with a Freedman-Robertson-Walker (FRW)…

An exact solution of the orbit equation for a massive particle in Schwarzschild metric
A. S. Ribeiro, F. N. Lima
In this paper, we consider a spherically curved symmetric spacetime to exact solving the orbit equation of a massive particle by using Jacobi's elliptic functions. Generally, the s…
