Relating $\beta'_*$ and $\gamma'_{Q*}$ in the ${\cal N}=1$ SQCD Conformal Window / Shifman, Mikhail (Minnesota U., Theor. Phys. Inst.) ; Zwicky, Roman (U. Edinburgh, Higgs Ctr. Theor. Phys. ; CERN)
In this note we show that $\beta'_*$, the $\beta$-function slopes in the electric and magnetic theories are equal at the corresponding infrared fixed points. [...]

An elliptic integrable deformation of the Principal Chiral Model / Lacroix, Sylvain ; Wallberg, Anders
We introduce a new elliptic integrable $\sigma$-model in the form of a two-parameter deformation of the Principal Chiral Model on the group $\text{SL}_{\mathbb{R}}(N)$, generalising a construction of Cherednik for $N=2$ (up to reality conditions). [...]
