LOGARITHMIC POTENTIAL BRANEWORLD IN LIGHT OF THE RECENT EXPERIMENT OBSERVATION.
In the loop inflation standard case, the spectral index n depends only on the e-folds number N; and it is larger than the value given by observational measurements. The ratio of tensor to scalar perturbations r is very small so that the gravitational waves are negligible. Therefore, we reconsider th...

The ratio of tensor to scalar perturbations r is very small so that the gravitational waves are negligible. Therefore, we reconsider this model in the framework of the Randall-Sundrum II braneworld scenario. In this context, we have computed and discussed the perturbation of the scalar curvature and determined the energy scale V; and the brane tension value λ: We showed that the various inflationary spectrum perturbation parameters (n; r and dn d ln k ) depend on N and on the coupling constant α, and we reproduce the central value of the first parameter n ~ 0.96. Also, the ratio r and the running dns d ln k are in perfect agreement with the experimental observations (Planck 2015). En el caso estándar de inflación de bucle, el índice espectral n solo depende del número de pliegues N, y es más grande que el valor dado por las mediciones de observación. La relación r de tensor a perturbaciones escalares es muy pequeña, de modo que las ondas gravitatorias son insignificantes. Por lo tanto, reconsideramos este modelo en el marco del escenario del Mundo-Brana de Randall-Sundrum II. En este contexto, hemos calculado y discutido la perturbación de la curvatura escalar y hemos determinado la escala de energía V; y el valor de la tensión de brana λ. Mostramos que los diversos parámetros de perturbación del espectro inflacionario (n, r y dn=d(ln[k])) dependen de N y de la constante de acoplamiento α, y reproducimos el valor central del primer parámetro n ~ 0:96. Además, la relación r y el desplazamiento dn=d(ln[k]) están en perfecto acuerdo con las observaciones experimentales (Planck 2015). pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y custom: Copyright of Revista Cubana de Física is the property of Universidad de La Habana and its content may not be copied or emailed to multiple sites without the copyright holder's express written permission.
