${\cal N}=1$ SQCD中的质谱图,带有额外的无色区域。强耦合机制。II

Mass spectra in ${\cal N}=1$ SQCD with additional colorless fields. Strong coupling regimes. II

Victor L. Chernyak

摘要:

本文继续我们在arXIV:1608.06452 [hep-th]中对强耦合区${\cal N}=1$规范理论的研究。我们在这里还考虑了具有$SU(N_c)$颜色(及其Seiberg对偶)的类似${\cal N}=1$ SQCD的理论,具有轻夸克的$N_F$味道和$N_F^2$额外的无色味道标量$Φ^j_i$,但现在$N_F$在$N_F>3N_c$范围内。在作者在[8]中介绍的动力学方案中计算了这些直接理论和对偶理论在各种真空中的质量谱。它假定在这种没有初等色伴随标量的${\cal N}=1$ SQCD类理论中夸克只能处于两个{ \it标准}相。它们要么是被限制的HQ(重夸克)相,要么是希格斯相。回想一下,这个场景满足了所有那些检验,这些检验被用来检验关于直接理论和对偶理论等价性的塞贝格假设。计算的直接$SU(N_c)$理论的质谱相比,其Seiberg的双$SU(N_F-N_c)$变体,似乎是参数不同。

英文摘要:

This paper continues our studies in arXiV:1608.06452 [hep-th] of ${\cal N}=1$ gauge theories in the strongly coupled regimes. We also consider here the ${\cal N}=1$ SQCD-like theories with $SU(N_c)$ colors (and their Seiberg's dual), with $N_F$ flavors of light quarks and $N_F^2$ additional colorless flavored scalars $Φ^j_i$, but now with $N_F$ in the range $N_F>3N_c$. The mass spectra of these direct and dual theories in various vacua are calculated within the dynamical scenario introduced by the author in [8]. It assumes that quarks in such ${\cal N}=1$ SQCD-like theories without elementary colored adjoint scalars can be in two {\it standard} phases only. These are either the HQ (heavy quark) phase where they are confined or the Higgs phase. Recall that this scenario satisfies all those tests which were used as checks of the Seiberg hypothesis about the equivalence of the direct and dual theories. Calculated mass spectra of the direct $SU(N_c)$ theory are compared to those of its Seiberg's dual $SU(N_F-N_c)$ variant and appeared to be parametrically different.
