关于4dN =2理论标度极限的评论

Comments on scaling limits of 4d N=2 theories

Davide Gaiotto, Nathan Seiberg, Yuji Tachikawa

摘要:

我们重新研究了4dN = 2SU(N)规范理论库仑分支的最大奇点<2N. When n >,发现低能物理是由两个非平凡的超共形场论耦合到一个无红外线的SU(2)规范群上来描述的. (In在n=2的特殊情况下,这些理论之一是自由超多重态理论。这一观察消除了一个可能的反例,以证明一个定理。

英文摘要:

We revisit the study of the maximally singular point in the Coulomb branch of 4d N=2 SU(N) gauge theory with N_f=2n flavors for N_f<2N. When n >= 2, we find that the low-energy physics is described by two non-trivial superconformal field theories coupled to a magnetic SU(2) gauge group which is infrared free. (In the special case n=2, one of these theories is a theory of free hypermultiplets.) This observation removes a possible counter example to a conjectured a-theorem.
