关于ABJM的N=6 Chern-Simons物质理论中类重子算子的注记

Comments on Baryon-like Operators in N=6 Chern-Simons-matter theory of ABJM

Chang-Soon Park

摘要:

我们证明了在Aharony,Bergman,Jafferis和Maldacena(ABJM)构造的N=6超共形Chern-Simons物质理论中存在类重子算符.这涉及到引进威尔逊(或特胡夫特)线结束的重子类运营商,我们表明,这种线的存在不能检测到的领域的理论。同样的构造可以用来使磁单极子在对角U(1)规范群下带电,并带有任意非整数荷。如果我们在路径积分中不包括这样的对称构型,则已知模空间由C^4/Z_k的对称N个副本给出。然而,如果我们允许这样的双组态,通量量子化条件改变,使得我们不具有离散的规范对称性,并且有效地保留了(SU(N)xSU(N))/Z_N规范理论。我们讨论了该理论的水平-秩对偶性的可能性。

英文摘要:

We show that baryon-like operators exist in the N=6 superconformal Chern-Simons-matter theory constructed by Aharony, Bergman, Jafferis and Maldacena (ABJM). This involves the introduction of Wilson(or 't Hooft) lines ending on baryon-like operators and we show that the presence of such lines cannot be detected by the fields in the theory. The same construction can be used to make magnetic monopoles charged under the diagonal U(1) gauge group with arbitrary non-integral charge. If we do not include such monopole configurations in the path integral, the moduli space is known to be given by the symmetric N copies of C^4/Z_k. However, if we allow for such monopole configurations, the flux quantization conditions change so that we do not have a discrete gauge symmetry and effectively the (SU(N)xSU(N))/Z_N gauge theory remains. We discuss the possibility of the level-rank duality of the theory.
