共形或限制

Conformal or Confining

Tiago Nunes da Silva, Elisabetta Pallante, Lasse Robroek

摘要:

我们提出了一个晶格研究的相变在零和非零温度的$SU(3)$规范理论与不同数量的味道$N_f$在规范群的基本表示。我们发现,所有的结果是一致的共形窗口之间的下边缘$N_f=8$和$N_f=6$。在这个区间的下沿是在显着的协议与微扰理论和最近的大$N$参数。.

英文摘要:

We present a lattice study of the phase transitions at zero and nonzero temperature for the $SU(3)$ gauge theory with a varying number of flavours $N_f$ in the fundamental representation of the gauge group. We show that all results are consistent with a lower edge of the conformal window between $N_f=8$ and $N_f=6$. A lower edge in this interval is in remarkable agreement with perturbation theory and recent large-$N$ arguments. .
