Effective action of a self-interacting scalar field on brane

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
In extra dimensional theories, the four-dimensional field theory is reduced from a fundamental field theory in the bulk spacetime by integrating the extra dimensional part.

Leptogenesis in theories with large extra dimensions [PDF]

open access: yesPhysical Review D, 1999
We study the scenario of baryogenesis through leptogenesis in higher-dimensional theories, in which the scale of quantum gravity is many orders of magnitude smaller than the usual Planck mass. The minimal realization of these theories includes an isosinglet neutrino which feels the presence of large compact dimensions, whereas all the SM particles are ...

Growing extra dimensions in AdS/CFT

open access: yesJournal of High Energy Physics, 2019
What is the dimension of spacetime? We address this question in the context of the AdS/CFT Correspondence. We give a prescription for computing the number of large bulk dimensions, D, from strongly-coupled CFT d data, where “large” means parametrically ...

Activated sphalerons and large extra dimensions [PDF]

open access: yesPhysical Review D, 2002
We present a new scenario for the baryon number violation that may take place in models with large extra dimensions. Our idea is interesting because leptogenesis with a low reheating temperature requires an alternative source of the B+L violation to convert the produced leptons into baryons.

Brane-World Gravity [PDF]

open access: yes, 2010
The observable universe could be a 1+3-surface (the “brane”) embedded in a 1+3+d-dimensional spacetime (the “bulk”), with Standard Model particles and fields trapped on the brane while gravity is free to access the bulk.

Singularity theorems for warped products and the stability of spatial extra dimensions

open access: yesJournal of High Energy Physics, 2019
New singularity theorems are derived for generic warped-product spacetimes of any dimension. The main purpose is to analyze the stability of (compact or large) extra dimensions against dynamical perturbations.
