Gauge Symmetry Reduction from the Extra Space
The study of physics beyond 4-dimensional (4D) space-time traces back to the work by Kaluza and Klein. 1) The exsitence of an extra space is essential in superstring theory 2), 3) and M -theory. 4) Recently, there is a lot of interesting research of the phenomenological and theoretical implications of an extra space with large radii based on several motivations. 5) As a feature in theories with...
متن کاملIneffective Supersymmetry: Electroweak Symmetry Breaking from Extra Dimensions
Recently, a mechanism for electroweak symmetry breaking (EWSB) was discussed [1], in which the scale of EWSB is set by the scale of an additional dimension R ∼ TeV. The mechanism involves supersymmetry, but broken in such a fashion that high (four-dimensional) momentum loops are cut off by the finite size of the radius. In a Kaluza-Klein decomposition, a hard cutoff seems to give a strong cutof...

متن کاملGauge symmetry breaking from extra space S 1 / Z 2
We study a mechanism of symmetry transition upon compactification of 5-dimensional field theory on S/Z2. The transition happens unless all components in a multiplet of a symmetry group have a common Z2 parity on S /Z2. This mechanism is applied to a breakdown of SU(5) gauge symmetry in grand unified theory and phenomenological implications are discussed. ∗e-mail: [email protected]
متن کاملBPS States with Extra Supersymmetry
A state saturating a BPS bound derived from a supersymmetry algebra preserves some fraction of the supersymmetry. This fraction of supersymmetry depends on the charges carried by the system, and we show that in general there are configurations of charges for which a BPS state would preserve more than half the original supersymmetry. We investigate configurations that could preserve 3/4 supersym...
