Exponentially large extra dimensions [PDF]
Physical Review D, 2002 We show how the presence of a very light scalar with a cubic self-interaction in six dimensions can stabilize the extra dimensions at radii which are naturally exponentially large, $r \sim \ell \exp [(4 )^3/g^2]$, where $\ell$ is a microscopic physics scale and $g$ is the (dimensionless) cubic coupling constant. The resulting radion mode of the metric

Large hierarchy from extra dimensions [PDF]
Physics Letters B, 2000 We argue that the familiar gauge hierarchy between the fundamental Planck scale M_{Pl} and the electroweak scale M_{W}, can be naturally explained in higher dimensional theories with relatively large radii (R_c > 1/M_{Pl}) extra dimensions. In particular, we show that it is possible that the electroweak Higgs mass at high energies is of the order of

Neutrinos confronting large extra dimensions [PDF]
Physics Letters B, 2001 We study neutrino physics in a model with one large extra dimension. We assume the existence of two four-dimensional branes in the five-dimensional space-time, one for the ordinary particles and the other one for mirror particles, and we investigate neutrino masses and mixings in this scheme.

Thick brane in Rastall gravity
Journal of High Energy Physics, 2022 In this work, thick branes in Rastall gravity are investigated. Three types of maximally symmetric thick brane models are constructed and the linear tensor perturbation is analyzed. In the flat brane model, the tensor modes of the perturbation are either

Large extra dimensions and neutrino experiments
Physical Review D, 2022 يمكن التحقق من وجود أبعاد إضافية كبيرة في تجارب النيوترينو المختلفة. نقوم بتحليل العديد من مجموعات بيانات النيوترينو في نموذج ذي بعد إضافي كبير مهيمن. نظهر أنه يمكن تفسير شذوذ الغاليوم بتذبذبات النيوترينو الناجمة عن البعد الإضافي الكبير، ولكن منطقة مساحة المعلمة التي يفضلها شذوذ الغاليوم متوترة مع الحدود من بيانات معدل المفاعل، وكذلك بيانات خليج دايا ...

Journal of High Energy Physics, 2021 In this paper we study shells of matter and black holes on the expanding bubbles realizing de Sitter space, that were proposed in [4]. We construct explicit solutions for a rigid shell of matter as well as black hole like solutions.

Emergent de Sitter cosmology near black hole horizon
Journal of High Energy Physics, 2022 We propose an effective model for an exponentially expanding universe in the brane-world scenario. The setup consists of a 5D black hole and a brane close to the black hole horizon.

Physics with large extra dimensions [PDF]
Nuclear Physics B - Proceedings Supplements, 2003 The recent understanding of string theory opens the possibility that the string scale can be as low as a few TeV. The apparent weakness of gravitational interactions can then be accounted by the existence of large internal dimensions, in the sub-millimeter region.
