High Quality Axion via a Doubly Composite Dynamics
Seung J. Lee, Yuichiro Nakai, Motoo Suzuki
We explore a new framework that furnishes a mechanism to simultaneously address the electroweak naturalness problem and the axion high quality problem. The framework is based on a…
Multiple Hierarchies from a Warped Extra Dimension
Seung J. Lee, Yuichiro Nakai, Motoo Suzuki
Theories beyond the Standard Model often contain mass scales hierarchically different from the electroweak scale and the Planck scale. It has been shown that such hierarchical mass…
Supersymmetric Alignment Models for
Yuichiro Nakai, Matthew Reece, Motoo Suzuki
Hierarchical masses of quarks and leptons are addressed by imposing horizontal symmetries. In supersymmetric Standard Models, the same symmetries play a role in suppressing flavor…
Spontaneous CP Violation and Horizontal Symmetry in the MSSM: Toward Lepton Flavor Naturalness
Daniel Aloni, Pouya Asadi, Yuichiro Nakai +2
We study the contributions of supersymmetric models with a horizontal symmetry and only spontaneous CP breaking to various lepton flavor observables, such as and t…
Electroweak-like Baryogenesis with New Chiral Matter
Kohei Fujikura, Keisuke Harigaya, Yuichiro Nakai +1
We propose a framework where a phase transition associated with a gauge symmetry breaking that occurs (not far) above the electroweak scale sets a stage for baryogenesis similar to…
Axion Quality from Superconformal Dynamics
Yuichiro Nakai, Motoo Suzuki
We discuss a possibility that a superconformal dynamics induces the emergence of a global symmetry to solve the strong CP problem through the axion. Fields spontane…
