Energy Transfer between Throats from a 10d Perspective
B. v. Harling, A. Hebecker, T. Noguchi
Strongly warped regions, also known as throats, are a common feature of the type IIB string theory landscape. If one of the throats is heated during cosmological evolution, the ene…
Gravitational Kaluza-Klein Modes in Warped Superstring Compactification
Tatsuya Noguchi, Masahiro Yamaguchi, Masakazu Yamashita
The Kaluza-Klein (KK) modes of graviton are studied in the IIB superstring compactification where the warped geometry is realized at the Klebanov-Strassler (KS) throat. Knowledge o…
Hierarchical Quark Masses and Small Mixing Angles from Warped Intersecting Brane Models
Tatsuya Noguchi
We propose a novel mechanism for reproducing the realistic hierarchical structure of the observed CKM mixing matrix and quark masses by means of introducing a warped metric. We ill…
Yukawa Hierarchy Transfer Based on Superconformal Dynamics and Geometrical Realization in String Models
Tatsuo Kobayashi, Hiroaki Nakano, Tatsuya Noguchi +1
We propose a scenario that leads to hierarchical Yukawa couplings and degenerate sfermion masses at the same time, in the context of extra-dimensional models, which can be naturall…
Sfermion Mass Degeneracy, Superconformal Dynamics and Supersymmetric Grand Unified Theories
Tatsuo Kobayashi, Hiroaki Nakano, Tatsuya Noguchi +1
We discuss issues in a scenario that hierarchical Yukawa couplings are generated through strong dynamics of superconformal field theories (SCFTs). Independently of mediation mechan…
Brane Fluctuation and New Counting Rules for Kaluza-Klein Towers
Masako Bando, Tatsuya Noguchi
In models with extra dimensions, branes have been usually treated as solid bodies though they are prohibited by the relativity. In the previous letter, we proposed a method of taki…
