Massive Spin-2 fields of Geometric Origin in Curved Spacetimes
V. P. Nair, S. Randjbar-Daemi, V. Rubakov
We study the consistency of a model which includes torsion as well as the metric as dynamical fields and has massive spin-2 particle in its spectrum. The massive spin-2 mode reside…
Primordial perturbations from slow-roll inflation on a brane
Kazuya Koyama, Andrew Mennim, V. A. Rubakov +2
In this paper we quantise scalar perturbations in a Randall-Sundrum-type model of inflation where the inflaton field is confined to a single brane embedded in five-dimensional anti…
Gauge theory solitons on noncommutative cylinder
S. V. Demidov, S. L. Dubovsky, V. A. Rubakov +1
We generalize to noncommutative cylinder the solution generation technique, originally suggested for gauge theories on noncommutative plane. For this purpose we construct partial i…
Quasi-localized states on noncommutative solitons
S. L. Dubovsky, V. A. Rubakov, S. M. Sibiryakov
We consider noncommutative gauge theories which have zero mass states propagating along both commutative and noncommutative dimensions. Solitons in these theories generically carry…
Gravity waves from inflating brane or Mirrors moving in adS
D. S. Gorbunov, V. A. Rubakov, S. M. Sibiryakov
We study tensor perturbations in a model with inflating Randall--Sundrum-type brane embedded in five-dimensional anti-de Sitter (adS) bulk. In this model, a natural {\it in}-va…
On models of gauge field localization on a brane
S. L. Dubovsky, V. A. Rubakov
We argue that any viable mechanism of gauge field localization should automatically imply charge universality on the brane. We study whether this condition is satisfied in the two…
Brane world: disappearing massive matter
S. L. Dubovsky, V. A. Rubakov, P. G. Tinyakov
In a brane (domain wall) scenario with an infinite extra dimension and localized gravity, bulk fermions and scalars often have bound states with zero 4-dimensional mass. In this wa…
Opening up extra dimensions at ultra-large scales
Ruth Gregory, Valery A. Rubakov, Sergei M. Sibiryakov
The standard picture of viable higher-dimensional theories is that extra dimensions manifest themselves at short distances only, their effects being negligible at scales larger tha…
