Title: Gravitating multidefects from higher dimensions

Abstract

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 nontopological solitons, and bound configurations of a kink and of a nontopological soliton. In all the mentioned cases the geometry is always well behaved (all relevant curvature invariants are regular) and tends to five-dimensional anti-de Sitter space-time for large asymptotic values of the bulk coordinate. Particular classes of solutions can be generalized to the framework where the gravity part of the action includes, as a correction, the Euler-Gauss-Bonnet combination. After scrutinizing the structure of the zero modes, the obtained results are compared with conventional gravitating configurations containing a single topological defect.

  • It is shown that surface integrals, involving gauge and Higgs fields, in both odd and even dimensions can be obtained by dimensional reduction from Chern classes in higher dimensions. For odd dimensions, the physically useful dimensional reduction is characterized by M/sub N/ = E/sub N/-p x S/sup p/, and for even dimensions by M/sub N/ = E/sub N/-p x S/sup 2/ x x x x x S/sup 2/ ( 1/2 p times). The existence of a family of field configurations for which these surface integrals in three dimensions exist, and are nonzero, is presented. This family includes a Yang--Mills--Higgs (YMH)more » system with an algebra-valued Higgs field and one with the Higgs field in the reducible representation adjoint direct-sum scalar.« less
  • A study is made of gauge theories obtained by dimensional reduction of multidimensional free gauge theories with symmetry. A sufficient condition for the reduced theory to contain only one irreducible multiplet of scalar fields is found. For the classes of such theories the potentials of scalar fields, Higgs potentials, are calculated explicitly. It is shown that in this approach the boson sector of the Weinberg-Salam model can be obtained. Stringent predictions for the mass of the Higgs boson and the Weinberg angle then arise - they can take only a discrete series of values.
  • In this paper, the authors show that classical U[infinity] gauge theories can be obtained from the dimensional reduction of a certain class of higher-derivative theories. In general, the exact symmetry is attained in the limit of degenerate metric; otherwise, the infinite-dimensional symmetry can be taken as spontaneously broken. Monopole solutions are examined in the model for scalar and gauge fields. An extension to gravity is also discussed.

  • We develop a scenario in which feeble intermediate-range forces emerge as an effect resulting from the compactification (a-italic-grave-accent l-italica-italic Kaluza-Klein) of a five-dimensional model. It is conjectured that this general strategy will prove applicable to more realistic multidimensional theories such as the ten-dimensional superstring. We speculate that deviations from the standard gravitational force: similar to the ones reported recently as a ''fifth force'': may be interpreted as evidence for higher dimensions.
