Gravity and Large Extra Dimensions

open access: yesAdvances in Astronomy, 2011
The idea that quantum gravity can be realized at the TeV scale is extremely attractive to theorists and experimentalists alike. This proposal leads to extra spacial dimensions large compared to the Planck scale.

Signatures of Large Extra Dimensions [PDF]

open access: yesInternational Journal of Modern Physics D, 2004
String theory suggests modifications of our spacetime such as extra dimensions and the existence of a mininal length scale. In models with addidional dimensions, the Planck scale can be lowered to values accessible by future colliders. Effective theories which extend beyond the standart-model by including extra dimensions and a minimal length allow ...

Exponentially large extra dimensions [PDF]

open access: yesPhysical 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]

open access: yesPhysics 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]

open access: yesPhysics 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

open access: yesJournal 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

open access: yesPhysical 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 ...

COSMIC RAYS AND LARGE EXTRA DIMENSIONS [PDF]

open access: yesRecent Developments in Gravity, 2003
We have proposed that the cosmic ray spectrum "knee", the steepening of the cosmic ray spectrum at energy $E \gsim 10^{15.5}$ eV, is due to "new physics", namely new interactions at TeV cm energies which produce particles undetected by the experimental apparatus.
