Non-invertible symmetries along 4d RG flows

Understand

We explore novel examples of RG flows preserving a non-invertible self-duality symmetry.

• Our main focus is on $\mathcal{N}=1$ quadratic superpotential deformations of 4d $\mathcal{N}=4$ super-Yang-Mills theory with gauge algebra $\mathfrak{su}(N)$.
• A theory that can be obtained in this way is the so-called $\mathcal{N}=1^*$ SYM where all adjoint chiral multiplets have a mass.
• Such IR theory exhibits a rich structure of vacua which we thoroughly examine.
