CP-violating phases in the CKM matrix in orbifold compactifications
The picture of CP-violation in orbifold compactifications in which the T-modulus is at a complex fixed point of the modular group is studied. CP-violation in the neutral kaon system and in the neutron electric dipole moment are both discussed. The situation where the T-modulus takes complex values on the unit circle which are not at a fixed point is also discussed.
متن کاملMagnetized orbifold models
We study (4+2n)-dimensional N=1 super Yang-Mills theory on the orbifold background with non-vanishing magnetic fluxes. In particular, we study zero-modes of spinor fields. The flavor structure of our models is different from one in magnetized torus models, and would be interesting in realistic model building.

متن کاملBreaking CP and supersymmetry with orbifold moduli dynamics
We consider the stabilization of string moduli and resulting soft supersymmetry-breaking terms in heterotic string orbifolds. Among the results obtained are: formulae for the scalar interaction soft terms without integrating out the hidden sector gaugino condensate, which reduce to standard expressions in the usual “truncated” limit; an expression for the modular transformation of A-terms; a st...
متن کاملSpectra in Standard-like Z3 Orbifold Models
General features of the spectra of matter states in all 175 models found in a previous work by the author are discussed. Only twenty patterns of representations are found to occur. Accomodation of the Minimal Supersymmetric Standard Model (MSSM) spectrum is addressed. States beyond those contained in the MSSM and nonstandard hypercharge normalization are shown to be generic, though some models ...
متن کاملThree generation magnetized orbifold models
We study three generation models in the four-dimensional spacetime, which can be derived from the ten-dimensional N = 1 super Yang-Mills theory on the orbifold background with a non-vanishing magnetic flux. We classify the flavor structures and show possible patterns of Yukawa matrices. Some examples of numerical studies are also shown. E-mail address: [email protected] E-mail address...
