R-symmetries from higher dimensions

Symmetries of Julia sets in higher dimensions

No - scale supergravity from higher dimensions 1 R . D ’ Auria

We discuss recent results on the interpretation of flux compactifications on certain Type IIB orientifolds in terms of gauged N –extended supergravities of no–scale type

Large hierarchies from approximate R symmetries.

We show that hierarchically small vacuum expectation values of the superpotential in supersymmetric theories can be a consequence of an approximate R symmetry. We briefly discuss the role of such small constants in moduli stabilization and understanding the huge hierarchy between the Planck and electroweak scales.

Gravitating multidefects from higher dimensions

Warped configurations admitting pairs of gravitating defects are analyzed. After devising a general method for the construction of multidefects, specific examples are presented in the case of higher-dimensional Einstein-Hilbert gravity. The obtained profiles describe diverse physical situations such as (topological) kink-antikink systems, pairs of non-topological solitons and bound configuratio...

Flavorful Supersymmetry from Higher Dimensions

We present models of flavorful supersymmetry in higher dimensions. The Higgs fields and the supersymmetry breaking field are localized in the same place in the extra dimension(s). The Yukawa couplings and operators generating the supersymmetry breaking parameters then receive the same suppression factors from the wavefunction profiles of the matter fields, leading to a specific correlation betw...
