源自IKKT矩阵模型的量子$\u200b\mathfrak{hs}$-Yang-Mills理论

Quantum $\mathfrak{hs}$-Yang-Mills from the IKKT matrix model

Harold C. Steinacker, Tung Tran

AI总结:

本研究基于IKKT矩阵模型,在FLRW时空膜与紧致模糊额外维度的背景下,通过量子效应使非阿贝尔高自旋规范场获得质量,构造出有质量的非阿贝尔量子高自旋杨-米尔斯理论,并揭示了额外维度稳定及超共形对称性破缺的机制。

摘要:

我们研究了IKKT矩阵模型在$\mathcal{M}^{1,3}\times \mathcal{K}$背景下诱导的高自旋规范理论的单圈有效作用量,其中$\mathcal{M}^{1,3}$是FLRW宇宙时空膜,$\mathcal{K}$是紧致模糊额外维度。特别地,我们证明该模型中所有非阿贝尔(取值于$\mathfrak{hs}$的)规范场都通过量子效应获得质量,从而避开了不可行定理。这催生了一种有质量的非阿贝尔量子$\mathfrak{hs}$-Yang-Mills理论,其详细结构依赖于$\mathcal{K}$。$\mathcal{K}$在单圈下的稳定可理解为$\mathcal{K}$与时空上$U(1)$通量丛耦合的结果。这种通量稳定将KK标度引入模型的$\mathcal{N}=4$ SYM扇区,打破了超共形对称性。

英文摘要:

We study the one-loop effective action of the higher-spin gauge theory induced by the IKKT matrix model on a $\mathcal{M}^{1,3}\times \mathcal{K}$ background, where $\mathcal{M}^{1,3}$ is an FLRW cosmological spacetime brane and $\mathcal{K}$ are compact fuzzy extra dimensions. In particular, we show that all non-abelian ($\mathfrak{hs}$-valued) gauge fields in this model acquire mass via quantum effects, thus avoiding no-go theorems. This leads to a massive non-abelian quantum $\mathfrak{hs}$-Yang-Mills theory, whose detailed structure depends on $\mathcal{K}$. The stabilization of $\mathcal{K}$ at one loop is understood as a result of the coupling between $\mathcal{K}$ and the $U(1)$-flux bundle on space-time. This flux stabilization induces the KK scale into the $\mathcal{N} = 4$ SYM sector of the model, which break superconformal symmetry.
