Cosmological Constant Probing Shape Moduli through Large Extra Dimensions
Satoshi Matsuda, Shigenori Seki
We consider compactification of extra dimensions and numerically calculate Casimir energy which is provided by the mass of Kaluza-Klein modes. For the extra space we consider a tor…
Proposal for Generic Size of Large Extra Dimensions
Satoshi Matsuda, Shigenori Seki
In order to resolve the hierarchy problem, large extra dimensions have been introduced, and it has been suggested that the size of extra dimensions is sub-millimeter. On the other…
Gravitational Stability and Screening Effect from Extra Timelike Dimensions
Satoshi Matsuda
We discuss extra timelike dimensions and their effects on the gravitational stability of spherical massive bodies. Here we specifically report our results for the case of one extra…
Gravitational Stability and Extra Timelike Dimensions
Satoshi Matsuda, Shigenori Seki
Tachyonic Kaluza-Klein modes normally appear from the compactification of extra timelike dimensions with scale and lead to some instabilities of physical systems. We calculate…
Gravitational Stability and Screening Effect from D Extra Timelike Dimensions
Satoshi Matsuda, Shigenori Seki
We study (3+1)+D dimensional spacetime, where D extra dimensions are timelike. Compactification of the D timelike dimensions leads to tachyonic Kaluza-Klein gravitons. We calculate…
Spectral Flow and Feigin-Fuks Parameter Space of N=4 Superconformal Algebras
Satoshi Matsuda
The parameter space of the Feigin-Fuks representations of the N=4 SU(2) superconformal algebras is studied from the viewpoint of the specral flow. The phase of the spectral…
