近日，日本九州大学Otsuka, Hajime团队研究了交叉/磁化D-膜模型中不可逆风味对称性的量子方面。2025年4月23日出版的《高能物理杂志》发表了这项成果。

研究组讨论了环形圆盘上IIA型相交和IIB型磁化D膜模型中手性物质的选择规则。由于环形球形物上的手性物质由测量球形物群的某一共轭类标记，因此选择规则涉及非平凡的融合规则。他们发现，手性物质的表示在树级上由偶数个磁通量或绕组数的D₄味对称性来描述。此外，即使考虑到环路效应，D₄对称性仍然存在。他们还研究了非微扰效应，如D-膜瞬子。

Abstract: 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.
