Compact extra dimensions in cosmologies with f(T) structure
(American Physical Society, 2014-01-22)
The presence of compact extra dimensions in cosmological scenarios in the context of f(T)-like gravities is discussed. For the case of toroidal compactifications, the analysis is performed in an arbitrary number of extra ...
Variation in the luminosity of Kerr quasars due to an extra dimension in the brane Randall-Sundrum model
(Iop Publishing LtdBristolInglaterra, 2005)
Topological interactions in warped extra dimensions
Topological interactions will be generated in theories with compact extra dimensions where fermionic chiral zero modes have different localizations. This is the case in many warped extra dimension models where the right-handed ...
Effects of large extra dimensions on cosmogenic neutrino fluxes
(Iop Publishing, 2013-05)
We study the consequences of theories with extra dimensions and a gravity scale of a few TeVs on the cosmogenic flux of neutrinos. Taking into account the most recent upper limits for the onset of the gravity effects given ...
On dilatons and the LHC diphoton excess
We study soft wall models that can embed the Standard Model and a naturally light dilaton. Exploiting the full capabilities of these models we identify the parameter space that allows to pass Electroweak Precision Tests ...
Shortcuts in particle production in a toroidally compactified space-time
We investigate the particle production in a toroidally compactified space-time due to the expansion of a Friedmann cosmological model in ℝ3 × S1 outside a U(1) local cosmic string. The case of a Friedmann space-time is ...
Extra dimensions at the CERN LHC via mini-black holes: Effective Kerr-Newman brane-world effects
(American Physical Soc, 2006-09-01)
We solve Einstein equations on the brane to derive the exact form of the brane-world-corrected perturbations in Kerr-Newman singularities, using Randall-Sundrum and Arkani-Hamed-Dimopoulos-Dvali (ADD) models. It is a ...
