Revisiting universal extra-dimension model with gravity mediated decays

Journal of High Energy Physics
We explore the collider phenomenology of the fat-brane realization of the Minimal Universal Extra Dimension (mUED) model, where Standard Model (SM) fields propagate in a small extra dimension while gravity accesses additional large extra dimensions. This

Probing large extra dimension at DUNE using beam tunes

Journal of High Energy Physics
The Deep Underground Neutrino Experiment (DUNE) is a leading experiment in neutrino physics which is presently under construction. DUNE aims to measure the yet unknown parameters in the three flavor oscillation case which includes discovery of leptonic ...

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, $r \sim \ell \exp [(4π)^3/g^2]$, where $\ell$ is a microscopic physics scale and $g$ is the (dimensionless) cubic coupling constant.

Extra dimensions with light and heavy neutral leptons: an application to CEνNS

Journal of High Energy Physics, 2023
We explore the possibility of relating extra dimensions with light and heavy Dirac-type neutral leptons and develop a framework for testing them in various laboratory experiments.

COSMIC RAYS AND LARGE EXTRA DIMENSIONS [PDF]

Recent 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.

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 ...

OBSERVABLES FROM LARGE EXTRA DIMENSIONS [PDF]

International Journal of Modern Physics D, 2004
The existence of extra dimensions and a minimal length scale are modifications of our spacetime which are suggested by string theory. In models with additional dimensions, the Planck scale can be lowered to values accessible by future colliders and in ultra high energetic cosmic rays.

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
