The Hierarchy Problem and New Dimensions at a Millimeter [PDF]
We propose a new framework for solving the hierarchy problem which does not rely on either supersymmetry or technicolor. In this framework, the gravitational and gauge interactions become united at the weak scale, which we take as the only fundamental ...

Gravity, scale invariance and the hierarchy problem [PDF]
Abstract Combining the quantum scale invariance with the absence of new degrees of freedom above the electroweak scale leads to stability of the latter against perturbative quantum corrections. Nevertheless, the hierarchy between the weak and the Planck scales remains unexplained.

A Machian solution of the hierarchy problem [PDF]
The new interpretation of Mach's principle of mass of a particle being a measure of the interactions of this particle with all other gravitating particles inside its causal spheres is introduced. It is shown that within some alternative model of gravitation that incorporates this principle, the Machian influence of the universe can reduce Planck's ...

Dark energy and the hierarchy problem [PDF]
The well-known hierarchy between the Planck scale (~10^{19}GeV) and the TeV scale, namely a ratio of ~10^{16} between the two, is coincidentally repeated in a inverted order between the TeV scale and the dark energy scale at \~10^{-3}eV implied by the ...

Do experiments suggest a hierarchy problem? [PDF]
The hierarchy problem of the scalar sector of the standard model is reformulated, emphasizing the role of experimental facts that may suggest the existence of a new physics large mass scale, for instance indications of the instability of the matter, or ...

Hiding the little hierarchy problem in the NMSSM [PDF]
In this paper we consider a set of soft supersymmetry breaking terms within the NMSSM which leads to a small hierarchy between the supersymmetry breaking scale and the electroweak scale. Specifically only the gaugino masses and the soft term in the Higgs

The omega-inequality problem for concatenation hierarchies of star-free languages [PDF]
The problem considered in this paper is whether an inequality of omega-terms is valid in a given level of a concatenation hierarchy of star-free languages.

Comments on the Hierarchy Problem in Effective Theories [PDF]
We discuss aspects of the hierarchy problem in effective theories with light scalars and a large, physical ultraviolet (UV) cutoff. We make two main points: (1) The (naive) fine-tuning observed in an effective theory does not automatically imply that the

Solving the Hierarchy Problem with Noncompact Extra Dimensions [PDF]
We show that gravitational effects of global cosmic 3-branes can be responsible for compactification from six to four space-time dimensions, naturally producing the observed hierarchy between electroweak and gravitational forces. The finite radius of the

Little Higgs Models: New Approaches to the Hierarchy Problem [PDF]
In this note we present a review of the little Higgs models that stabilize the electroweak by realizing the Standard Model Higgs as a pseudo-Goldstone boson.Comment: Proceedings for ICHEP02, 3 pages, 2 ...
