来自M5-branes的风味

Flavor from M5-branes

Bartomeu Fiol

摘要:

我们研究了在AdS_4 x S^7中放置单个M5膜探针时出现的缺陷共形场论的各个方面。我们推导出了相应对偶算子的涨落模和维数的全集合。我们认为,后者并不依赖于存在一个非平凡的磁通量的M5膜世界体积。最后,我们给出了生活在缺陷上的超多重态的质量,并计算了由此产生的介子谱。

英文摘要:

We study various aspects of the defect conformal field theory that arises when placing a single M5-brane probe in AdS_4 x S^7. We derive the full set of fluctuation modes and dimensions of the corresponding dual operators. We argue that the latter does not depend on the presence of a non-trivial magnetic flux on the M5-brane world-volume. Finally we give a mass to the hypermultiplet living on the defect, and compute the resulting mesonic spectrum.
