Deformed two-point correlators in mixed TbarT/root-TbarT CFTs admit an explicit kernel representation as weighted averages of undeformed CFT correlators over conformal dimensions, with the two-point function obtained to all orders in TbarT and leading order in root-TbarT.

Series expansions are obtained for multiple Mellin-Barnes integrals representing basis kernels in the Schwinger-DeWitt asymptotic expansions of operator functions, with separate treatments for non-resonant and resonant cases and a suggested physical link to UV/IR properties.

Correlators in $T\bar{T}$ and Root-$T\bar{T}$ Deformed CFTs
Deformed two-point correlators in mixed TbarT/root-TbarT CFTs admit an explicit kernel representation as weighted averages of undeformed CFT correlators over conformal dimensions, with the two-point function obtained to all orders in TbarT and leading order in root-TbarT.

Multiple Mellin-Barnes integrals in Schwinger-DeWitt technique
Series expansions are obtained for multiple Mellin-Barnes integrals representing basis kernels in the Schwinger-DeWitt asymptotic expansions of operator functions, with separate treatments for non-resonant and resonant cases and a suggested physical link to UV/IR properties.
