Quantum effects, brane tension and large hierarchy in the brane-world
Abstract
Semiclassical Einstein's equation with conformally invariant bulk matter fields is examined in the brane world scenario with the S^1/Z_2 compactification. We obtain exact semiclassical solutions and suggest that it may be possible to take advantage of two different Randall-Sundrum scenarios by considering a positive tension for our brane and a fine-tuned tension for the hidden brane. Besides fine tuning of brane tensions, we obtain another necessary condition for this setting.Keywords
