Description

We compute the topological susceptibility of the \(\mathrm{SU}(N)\) Yang–Mills theory in the large-\(N\) limit with a percent level accuracy. This is achieved by measuring the gradient-flow definition of the susceptibility at three values of the lattice spacing for \(N=3\), \(4\), \(5\), \(6\). Thanks to this coverage of parameter space, we can extrapolate the results to the large-\(N\) and continuum limits with confidence. Open boundary conditions are instrumental to make simulations feasible on the finer lattices at the larger \(N\).
