The large $N$ limit of the topological susceptibility of Yang-Mills gauge theory
The large $N$ limit of the topological susceptibility of Yang-Mills gauge theory
We present a precise computation of the topological susceptibility $\chi_{_\mathrm{YM}}$ of SU$(N)$ Yang-Mills theory in the large $N$ limit. The computation is done on the lattice, using high-statistics Monte Carlo simulations with $N=3, 4, 5, 6$ and three different lattice spacings. Two major improvements make it possible to go to …
