  "abstract": "In this paper, we analyze the systems of screening charges corresponding to $η$-deformed $O(N)$ and $OSp(N|2m)$ sigma models. These sigma models can be represented as integrable deformations of certain conformal field theories. Based on the case of $O(N)$ sigma models, which were conjectured in previous works by A.V. Litvinov and co-authors to be an integrable deformation of the conformal field theory corresponding to the algebras $W(D(n+1|n))$ and $W(D(n|n))$ for the cases $N=2n+2$ and $N=2n+1$ at $n \\geq 1$, respectively, we formulate a hypothesis on how to write down the system of screening charges for the conformal field theory whose integrable deformation defines the $η$-deformed $OSp(N|2m)$ sigma model for the case of odd $N=2n+1$, asymptotically free models with $N-2m-2>0$ and $n \\geq 2$, $m \\geq 1$. This hypothesis is explicitly verified for the cases of $OSp(5|2)$, $OSp(7|2)$, and $OSp(7|4)$, which were separately investigated in the work of M.N. Alfimov and co-authors.",
