1/4 BPS弦结与6维(2,0)超共形理论中的$N^3$问题

1/4 BPS String Junctions and $N^3$ Problem in 6-dim (2,0) Superconformal Theories

Stefano Bolognesi, Kimyeong Lee

摘要:

我们研究了ADE型6-dim(2,0)超共形理论中库仑相的1/4 BPS天体。利用以前在5维规范理论和6维超共形理论中关于弦的结的工作,我们计算了由自对偶弦上的波和自对偶弦的结组成的1/4 BPS天体的数目,并证明了在所有情况下,这个数目都恰好与反常常数$c_G=d_G h_G$的三分之一相匹配,反常常数是维数$d_G$和对偶Coxeter数$h_G$的乘积.这表明,长期以来追求的$N^3$自由度是这些1/4 BPS对象至少在库仑相位。

英文摘要:

We explore 1/4 BPS objects in the Coulomb phase of the ADE-type 6-dim (2,0) superconformal theories. By using the previous work on the junctions of strings in 5-dim gauge theories and 6-dim superconformal theories, we count the number of 1/4 BPS objects, which are made of waves on selfdual strings and junctions of selfdual strings and show that for all cases the number matches exactly one third of the anomaly constant $c_G=d_G h_G$ which is the product of dimension $d_G$ and dual Coxeter number $h_G$. This suggests the long sought after $N^3$ degrees of freedom are these 1/4 BPS objects at least in the Coulomb phase.
