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 higherdimensional EinsteinHilbert gravity. The obtained profiles describe diverse physical situations such as (topological) kinkantikink 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 fivedimensional antide Sitter spacetime 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 EulerGaussBonnet 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 YangMillsHiggs (YMH)more »

Higgs potentials as inheritance from higher spacetime dimensions. II. Construction of Higgs models
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 WeinbergSalam 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. 
U([infinity]) gauge theory from higher dimensions
In this paper, the authors show that classical U[infinity] gauge theories can be obtained from the dimensional reduction of a certain class of higherderivative theories. In general, the exact symmetry is attained in the limit of degenerate metric; otherwise, the infinitedimensional 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. 

Feeble intermediaterange forces from higher dimensions
We develop a scenario in which feeble intermediaterange forces emerge as an effect resulting from the compactification (aitalicgraveaccent litalicaitalic KaluzaKlein) of a fivedimensional model. It is conjectured that this general strategy will prove applicable to more realistic multidimensional theories such as the tendimensional 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.
