T\bar{T} deformed CFTs are known to possess nonlocal conformal symmetries that do not act tractably on the undeformed local operators. I will talk about two distinct classes of operators: (i) dressed operators, which are primary operators with respect to the nonlocal conformal symmetries, and (ii) physical operators, a new type of local operator we introduce. The physical operators can be expressed in terms of the dressed operators, and give us more understanding to the non-local coordiantes. I will introduce how to calculate the correlation functions of these operators in momentum space and find that the results align with both string theory predictions and field theory calculations.
