Resumen

Se estudian los descriptores estadísticos (nivel de anisotropía estadística y niveles de no gaussianidad) de la perturbación primordial en la curvatura ζ para modelos cosmológicos inflacionarios que incluyen campos escalares y vectoriales, estos últimos propuestos para incluir violaciones de la isotropía estadística. Para estos modelos se encuentra que es posible obtener relaciones de consistencia entre los descriptores estadísticos, los cuales poseen una contraparte observacional y que, por ende, permiten validar o desechar un modelo teórico. Finalmente, se muestra que los resultados obtenidos están de acuerdo con los datos observacionales más recientes. Como un subproducto de este estudio, presentamos en este artículo la definición del verdadero principio cosmológico.
