Phenomenological aspects of 10D SYM theory with magnetized extra dimensions

Abstract We present a particle physics model based on a ten-dimensional (10D) super Yang–Mills (SYM) theory compactified on magnetized tori preserving four-dimensional N = 1 supersymmetry. The low-energy spectrum contains the minimal supersymmetric standard model with hierarchical Yukawa couplings caused by a wavefunction localization of the chiral matter fields due to the existence of magnetic fluxes, allowing a semi-realistic pattern of the quark and the lepton masses and mixings. We show supersymmetric flavor structures at low energies induced by a moduli-mediated and an anomaly-mediated supersymmetry breaking.

Superfield description of 10D SYM theory with magnetized extra dimensions

Abstract We present a four-dimensional (4D) N = 1 superfield description of supersymmetric Yang–Mills (SYM) theory in ten-dimensional (10D) spacetime with certain magnetic fluxes in compactified extra dimensions preserving partial N = 1 supersymmetry out of full N = 4 . We derive a 4D effective action in N = 1 superspace directly from the 10D superfield action via dimensional reduction, and identify its dependence on dilaton and geometric moduli superfields. A concrete model for three generations of quark and lepton superfields are also shown. Our formulation would be useful for building various phenomenological models based on magnetized SYM theories or D-branes.

Gaussian Froggatt-Nielsen mechanism on magnetized orbifolds

We study the structure of Yukawa matrices derived from the supersymmetric Yang-Mills theory on magnetized orbifolds, which can realize the observed quark and charged lepton mass ratios as well as the Cabibbo-Kobayashi-Maswaka (CKM) mixing angles, even with a small number of tunable parameters and without any critical fine-tuning. As a reason behind this, we find that the obtained Yukawa matrices possess a Froggatt-Nielsen-like structure with Gaussian hierarchies, which provides a suitable texture for them favored by the experimental data.

Superfield description of (4+2n)-dimensional SYM theories and their mixtures on magnetized tori

= 1 supersymmetry. Recently, we constructed a semi-realistic model which contains the minimal supersymmetric standard model (MSSM) using an ansatz of magnetic fluxes and orbifolding projections. However, we can consider more various configurations of magnetic fluxes and orbifolding projections preserving fourdimensional

Nonuniversal gaugino masses in a magnetized toroidal compactification of SYM theories

A bstractWe study discrete flavor symmetries of the models based on a ten-dimensional supersymmetric Yang-Mills (10D SYM) theory compactified on magnetized tori. We assume non-vanishing non-factorizable fluxes as well as the orbifold projections. These setups allow model-building with more various flavor structures. Indeed, we show that there exist various classes of non-Abelian discrete flavor symmetries. In particular, we find that S3 flavor symmetries can be realized in the framework of the magnetized 10D SYM theory for the first time.

Dynamical supersymmetry breaking on magnetized tori and orbifolds

Abstract We provide a systematic way of dimensional reduction for ( 4 + 2 n ) -dimensional U ( N ) supersymmetric Yang–Mills (SYM) theories ( n = 0 , 1 , 2 , 3 ) and their mixtures compactified on two-dimensional tori with background magnetic fluxes, which preserve a partial N = 1 supersymmetry out of full N = 2 , 3 or 4 in the original SYM theories. It is formulated in an N = 1 superspace respecting the unbroken supersymmetry, and the four-dimensional effective action is written in terms of superfields representing N = 1 vector and chiral multiplets, those arise from the higher-dimensional SYM theories. We also identify the dilaton and geometric moduli dependence of matter Kahler metrics and superpotential couplings as well as of gauge kinetic functions in the effective action. The results would be useful for various phenomenological/cosmological model buildings with SYM theories or D-branes wrapping magnetized tori, especially, with mixture configurations of them with different dimensionalities from each other.
