Summary
M theory naturally produces warped geometries, similar to string theory. Compactifying AdS(7) dimensions reveals novel TeV scale string winding states, potentially detectable at the Large Hadron Collider.
Area of Science:
- Theoretical Physics
- High Energy Physics
- String Theory
Background:
- Warped geometries in 5D anti-de Sitter space (AdS(5)) arise from type IIB string theory.
- M theory provides a framework for AdS(7) warped geometries using M5 branes.
Purpose of the Study:
- To investigate the spectrum of a compactified AdS(7) space, specifically AdS(5) x Sigma(2).
- To explore potential experimental signatures of M theory at the Large Hadron Collider (LHC).
Main Methods:
- Compactification of two spatial dimensions of AdS(7) to form AdS(5) x Sigma(2).
- Analysis of the 5D spectrum for bulk scalars and gravitons in AdS(5) x T(2).
- Mimicking the Randall-Sundrum model setup.
Main Results:
- Identified novel features in the 5D spectrum.
- Obtained TeV scale string winding states without reducing the fundamental string scale.
- Observed double warping effects on winding states along compactified AdS directions.
Conclusions:
- The study presents unique signatures potentially observable at the LHC.
- Experimental verification of these AdS(7) signatures could provide direct evidence for M theory.
