摘要

讨论了环面轨道上IIA型交叉和IIB型磁化d膜模型中手性物质的选择规律。由于环面轨道上的手性物质是由测量轨道群的某一共轭类来标记的，因此选择规则涉及非平凡的融合规则。我们发现手性物质的表示是用树级磁通或圈数偶数的D4风味对称来描述的。此外，即使我们考虑到循环效应，D4对称性仍然存在。我们还研究了非微扰效应，如d膜瞬子。

Quantum aspects of non-invertible flavor symmetries in intersecting/magnetized D-brane models

We discuss selection rules of chiral matters in type IIA intersecting and IIB magnetized D-brane models on toroidal orbifolds. Since the chiral matters on toroidal orbifolds are labeled by a certain conjugacy class of the gauged orbifold group, the selection rules involve non-trivial fusion rules. We find that the representation of the chiral matters is described by a D₄ flavor symmetry for an even number of magnetic fluxes or winding numbers at tree level. Furthermore, the D₄ symmetry still remains even when we take into account loop effects. We also study non-perturbative effects such as D-brane instantons.

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
