Sparticle Masses in Product-Group Gauge Theories
Nobuhito Maru, Koichi Yoshioka
In this paper, we investigate a possibility to cause supersymmetry breaking with background modulus fields in product-group gauge theories. The vacuum expectation values of these m…

Radiative CP Phases in Supergravity Theories
Motoi Endo, Masahiro Yamaguchi, Koichi Yoshioka
In this letter, we point out that possible sources of CP violation originate from radiative corrections to soft terms which are ubiquitous in supergravity theories and also in othe…

Neutrino Masses and Mixing Matrix from SU(1,1) Horizontal Symmetry
Kenzo Inoue, Nao-aki Yamashita
A new mechanism is proposed to explain neutrino masses and their mixing via SU(1,1) horizontal symmetry breaking. Based on this mechanism smallness of neutrino masses is naturally…
