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.

Black holes at accelerators [PDF]

open access: yes, 2010
In theories with large extra dimensions and TeV-scale gravity, black holes are copiously produced in particle collisions at energies well above the Planck scale.

Physics with large extra dimensions [PDF]

open access: yesNuclear 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.

THE MINIMAL LENGTH AND LARGE EXTRA DIMENSIONS [PDF]

open access: yesModern Physics Letters A, 2004
Planck scale physics represents a future challenge, located between particle physics and general relativity. The Planck scale marks a threshold beyond which the old description of spacetime breaks down and conceptually new phenomena must appear. Little is known about the fundamental theory valid at Planckian energies, except that it necessarily seems ...

Astrophysical constraints on large extra dimensions [PDF]

open access: yesPhysics Letters B, 1999
In the Kaluza-Klein (KK) scenario with n large extra dimensions where gravity propagates in the 4+n dimensional bulk of spacetime while gauge and matter fields are confined to a four dimensional subspace, the light graviton KK modes can be produced in the Sun, red giants and supernovae. We study the energy-loss rates through photon-photon annihilation,
