摘要：

Motivated by multi-throat considerations, we study the phenomenological implications of a bulk axion in a slice of AdS(5) with a large extra dimension: k similar to 10(-2) eV, kR greater than or similar to O( 1). In particular, we compare axion physics with a warped geometry to axions in flat compactifications. As in flat compactification scenarios, we find that the mass of the axion can become independent from the underlying Peccei-Quinn scale. Surprisingly, we find that in warped extra dimensions the axion's invisibility, cosmological viability, and basic phenomenology remain essentially unaltered in comparison to axions in flat compactifications.
