A violação da invariância de Lorentz na cosmologia inflacionária.

Abstract

In this work, we investigate the impact of Lorentz invariance breaking in a cosmological scenario. In this sense, we show the possibility of superluminal neutrinos highly energetic in the presence of a constant field that controls the Lorentz symmetry violation. Investigate the effective metric in space with curvature k = 0 via metric Friedmann-Robertson-Walker and the other in space with curvature k 6= 0 in spherical coordinates, through analyzing a potential constant scaling factor and the deceleration parameter. A similar behavior, however, subluminal, is also observed from inflatons in the low energy regime. Therefore, this type of cosmological scenario can hold the idea of superluminal neutrinos and dark energy.
