Abstract: (Springer)
Since the definition of TTˉT\bar T deformation in the curved Riemann surface is obstructive in the literature, we propose a way to do the deformation in the genus two Riemann surfaces by sewing prescription. We construct the correlation functions of conformal field theories (CFTs) on genus two Riemann surfaces with the TTˉT\bar T deformation in terms of the perturbative CFT approach. Thanks to sewing construction to form higher genus Riemann surfaces from lower genus ones and conformal symmetry, we systematically obtain the first-order TTˉT\bar T correction to the genus two correlation functions in the TTˉT\bar T deformed CFTs, e.g., partition function and one/higher-point correlation functions.
