Scale setting of SU( $N$ ) Yang--Mills theory, topology and large- $N$ volume independence

Claudio Bonanno, Jorge Luis Dasilva Golán, Margarita García Pérez +2

We set the scale of SU( $N$ ) Yang--Mills theories for $N = 3, 5, 8$ and in the large- $N$ limit via gradient flow, as a first step towards the computation of the large- $N$ $Λ$ -parameter…
