Can the Hierarchy Problem Be Solved by Finite-temperature Massive Fermions in the Randall-sundrum Model?
نویسنده
چکیده
Quantum effects of bulk matter, in the form of massive fermions, are considered in the Randall-Sundrum AdS5 brane world at finite temperatures. The thermodynamic energy (modulus potential) is calculated in the limiting case when the temperature is low, and is shown to possess a minimum, thus suggesting a new dynamical mechanism for stabilizing the brane world. Moreover, these quantum effects may solve the hierarchy scale problem, at quite low temperatures. The present note reviews essentially the fermion-related part of the recent article by I. Brevik, K. A. Milton, S. Nojiri, and S. D. Odintsov, Nucl. Phys. B 599, 305 (2001). Submitted to Gravitation and Cosmology (G@C), special issue devoted to Quantum Gravity, Unified Models and Strings, to mark the 100th anniversary of Tomsk State Pedagogical University. Edited by Professor S. D. Odintsov. e-mail: [email protected] 1

A Solution of the Randall-Sundrum Model and the Mass Hierarchy Problem
Abstract A solution of the Randall-Sundrum model for a simplified case (one wall) is obtained. It is given by the 1/k-expansion (thin wall expansion) where 1/k is the thickness of the domain wall. The vacuum setting is done by the 5D Higgs potential and the solution is for a family of the Higgs parameters. The mass hierarchy problem is examined. Some physical quantities in 4D world such as the ...
متن کاملQuantum Corrections to the Kinetic Term in the Randall-Sundrum model
The effective action of the radion in the Randall-Sundrum model is analysed. Fine tunings are needed to obtain the observed mass hierarchy and an invisible radion. Since the kinetic terms are important for determining the radion mass, the finite quantum corrections from massless conformally coupled fermions are analysed and found to vanish at one loop order.
متن کاملRandall-Sundrum with Kalb-Ramond field: return of the hierarchy problem?
We show that when the antisymmetric Kalb-Ramond field is included in the Randall-Sundrum scenario, although the hierarchy problem can be solved, it requires an extreme fine tuning of the Kalb-Ramond field (about 1 part in 10). We interpret this as the return of the problem in disguise. Further, we show that the Kalb-Ramond field induces a small negative cosmological constant on the visible brane.
متن کاملQuantized bulk fermions in the Randall-Sundrum brane model
The lowest order quantum corrections to the effective action arising from quantized massive fermion fields in the Randall-Sundrum background spacetime are computed. The boundary conditions and their relation with gauge invariance are examined in detail. The possibility of Wilson loop symmetry breaking in brane models is also analyzed. The self-consistency requirements, previously considered in ...
