A small weak scale from a small cosmological constant
Abstract/Contents
- Abstract
- This thesis discusses a framework in which Weinberg's anthropic explanation of the cosmological constant problem also solves the higgs hierarchy problem. The weak scale is selected by chiral dynamics that controls the stabilization of an extra dimension. When the higgs vacuum expectation value is close to a fermion mass scale (the weak scale), the radius of an extra dimension becomes large, and develops an enhanced number of vacua available to scan the cosmological constant down to its observed value. At low energies, the radion, the particle that controls the size of the extra dimension, necessarily appears as an unnaturally light scalar, in a range of masses and couplings accessible to fifth-force searches as well as scalar dark matter searches with atomic clocks and gravitational-wave detectors. The fermion sector that controls the size of the extra dimension consists of a pair of electroweak doublets and several singlets. These leptons satisfy approximate mass relations related to the weak scale and are accessible to the LHC and future colliders.
