Logarithmic Potential Braneworld in Light of the Recent Experiment Observation %K %X In the loop inflation standard case, the spectral index n s 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 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 0 ; and the brane tension value λ. We showed that the various inflationary spectrum perturbation parameters (n s , r and dn s /d(ln k) ) depend on N and on the coupling constant α, and we reproduce the central value of the first parameter n s ∼ 0.96. Also, the ratio r and the running dn s /d(ln k) are in perfect agreement with the experimental observations (Planck 2015). %U https://www.revistacubanadefisica.org/index.php/rcf/article/view?path= %J Revista Cubana de Física %0 Journal Article %& 86 %P 5 %V 35 %N 2 %@ 2224-7939 %8 2018-12-15 %7 2018-12-14
