Conformal and gauge invariant spin-2 field equations
C. S. O. Mayor, G. Otalora, J. G. Pereira
Using an approach based on the Casimir operators of the de Sitter group, the conformal invariant equations for a fundamental spin-2 field are obtained, and their consistency discus…
Spin-2 fields and helicity
H. I. Arcos, C. S. O. Mayor, G. Otalora +1
By considering the irreducible representations of the Lorentz group, an analysis of the different spin-2 waves is presented. In particular, the question of the helicity is discusse…
de Sitter relativity: a natural scenario for an evolving Lambda
J. P. Beltran Almeida, C. S. O. Mayor, J. G. Pereira
The dispersion relation of de Sitter special relativity is obtained in a simple and compact form, which is formally similar to the dispersion relation of ordinary special relativit…
de Sitter Relativity and Quantum Physics
R. Aldrovandi, J. P. Beltran Almeida, C. S. O. Mayor +1
In the presence of a cosmological constant, interpreted as a purely geometric entity, absence of matter is represented by a de Sitter spacetime. As a consequence, ordinary Poincare…
Lorentz transformations in de Sitter relativity
R. Aldrovandi, J. P. Beltran Almeida, C. S. O. Mayor +1
The properties of Lorentz transformations in de Sitter relativity are studied. It is shown that, in addition to leaving invariant the velocity of light, they also leave invariant t…
