FLRW Universes from "Wave-Like" Cosmologies in 5D
J. Ponce de Leon
We consider the evolution of a 4D-universe embedded in a five-dimensional (bulk) world with a large extra dimension and a cosmological constant. The cosmology in 5D possesses "wave…
CP-violating Majorana phases, lepton-conserving processes and final state interactions
Jose F. Nieves, Palash B. Pal
The CP-violating phases associated with Majorana neutrinos can give rise to CP-violating effects even in processes that conserve total Lepton number, such as μ-> eee+, μ+ e -> e +…
Invariant definition of rest mass and dynamics of particles in 4D from bulk geodesics in brane-world and non-compact Kaluza-Klein theories
J. Ponce de Leon
In the Randall-Sundrum brane-world scenario and other non-compact Kaluza-Klein theories, the motion of test particles is higher-dimensional in nature. In other words, all test part…
Field theory of the photon self-energy in a medium with a magnetic field and the Faraday effect
Juan Carlos D'Olivo, Jose F. Nieves, Sarira Sahu
A convenient and general decomposition of the photon self-energy in a magnetized, but otherwise isotropic, medium is given in terms of the minimal set of tensors consistent with th…
Hydrostatic Equilibrium of a Perfect Fluid Sphere with Exterior Higher-Dimensional Schwarzschild Spacetime
J. Ponce de Leon, Norman Cruz
We discuss the question of how the number of dimensions of space and time can influence the equilibrium configurations of stars. We find that dimensionality does increase the effec…
Constraints on star formation theories from the Serpens molecular cloud and protocluster
L. Olmi, L. Testi
We have mapped the large-scale structure of the Serpens cloud core using moderately optically thick (13CO(1--0) and CS(2--1)) and optically thin tracers (C18O(1--0), C34S(2--1), an…
Variation of G, and Vacuum Energy From Brane-World Models
J. Ponce de Leon
In brane-world theory in five dimensions, the bulk metric is usually written in gaussian coordinates, where and . However, the choice is a…
