Constraints on unparticle long range forces from big bang nucleosynthesis bounds on the variation of the gravitational coupling
O. Bertolami, N. M. C. Santos
We use big bang nucleosynthesis bounds on the variation of the gravitational coupling to derive constraints on the strength of the deviation from the gravitational inverse-square l…
A Simple Quintessence Model
M. C. Bento, R. Gonzalez Felipe, N. M. C. Santos
A simple model of quintessential inflation with the modified exponential potential is analyzed in the braneworld context. Considering reheating via instant…
Brane assisted quintessential inflation with transient acceleration
M. C. Bento, R. Gonzalez Felipe, N. M. C. Santos
A simple model of quintessential inflation with the modified exponential potential exp(-αϕ) [A + (ϕ-ϕ_0)^2] is analyzed in the braneworld context. Considering reheating via instant…
Natural inflation in 5D warped backgrounds
R. Gonzalez Felipe, N. M. C. Santos
In light of the five-year data from the Wilkinson Microwave Anisotropy Probe (WMAP), we discuss models of inflation based on the pseudo Nambu-Goldstone potential predicted in five-…
Gravitino production in the Randall-Sundrum II braneworld cosmology
N. M. C. Santos
Braneworld modifications to the Friedmann expansion law can have an important effect on the cosmological evolution of the early universe. In particular, the primordial particle abu…
Braneworld inflation from an effective field theory after WMAP three-year data
M. C. Bento, R. Gonzalez Felipe, N. M. C. Santos
In light of the results from the WMAP three-year sky survey, we study an inflationary model based on a single-field polynomial potential, with up to quartic terms in the inflaton f…
