“…Similar results are also found in reference [8]. After get the numerical results for the eigenfunction and applied it to equation ( 23), in the hybrid Bloch brane case, we can set experimental bound in the same way that performed in reference [7]. So, we can adjust the models parameters in order to obtain suitable results endorsed by the Newton's Law.…”

“…In another models, this correction is dependent on more parameters, as the case of Resolved Conifold (RC) presented in reference [12]. The RC case is phenomenologically more interesting since that other parameters can be combined in order to satisfy simultaneously the hierarchy problem, the correction of Newton's Law and other issues [7].…”

Abstract. We present in this work, the calculations of corrections in the Newton's law of gravitation due to Kaluza-Klein gravitons in five-dimensional warped thick braneworld scenarios. We consider here a recently proposed model, namely, the hybrid Bloch brane. This model couples two scalar fields to gravity and is engendered from a domain wall-like defect. Also, two other models the so-called asymmetric hybrid brane and compact brane are considered. Such models are deformations of the φ 4 and sine-Gordon topological defects, respectively. Therefore we consider the branes engendered by such defects and we also compute the corrections in their cases. In order to attain the mass spectrum and its corresponding eigenfunctions which are the essential quantities for computing the correction to the Newtonian potential, we develop a suitable numerical technique. The calculation of slight deviations in the gravitational potential may be used as a selection tool for braneworld scenarios matching with future experimental measurements in high energy collisions 1. Introduction Phenomenological application to braneworld models is a very interesting current subject. As can be found in detail in the introduction of reference [1], we have recent works in the braneworld branch explaining the process in the meson B decay and in the neutrinos physics, setting bounds into corrections to Coulomb's law and into electrical conductivity. Selecting parameters to the experimental data of the nucleon-nucleus total cross-section of various chemical elements, and interesting applications to black holes and gravitational waves, are other examples.In this view, one of most famous scenarios is the Bloch brane [2]. This smooth model consists in a thick brane generated by two interacting scalar fields which solve several issues in the fields localisation present in thin models [3,4], especially in the context of gauge fields and fermion fields. The Bloch brane allows the existence of internal structures and a rich variety of scalar field deformations. So, there are many other models based on the initial proposal of the Bloch brane, such the degenerate Bloch brane [1] and recently the hybrid Bloch brane [5]. The term "hybrid" comes from the existence of an interval with compact structure [6]. One of the scalar fields that compose the Bloch model is the well-known kink solution, which describes a wide variety of physics phenomena by connecting smoothly two minima. Unlike the kink where the energy density vanishes asymptotically, a compact kink is a linear compact structure, with the energy density that vanishes outside a closed interval [6]. Then, the Bloch brane proposed in the reference [5] is the so-called hybrid, because exhibits a usual thick brane inside an interval and a compact solution outside of this interval. We analyse in this work the gravity localization
