On Yang-Mills Stability Bounds and Plaquette Field Generating Function

Paulo A. Faria da Veiga, Michael O'Carroll

We consider the Yang-Mills (YM) QFT with group $U(N)$. We take a finite lattice regularization $\Lambda \subset a{\mathbb{Z}}^d$, $d=2,3,4$, with $a\in (0,1]$ and $L$ (even) sites on a sid…
