Abstract: TTbar deformation is an important irrelevant deformation of 2d QFT which is exactly solvable. We consider TTbar deformed conformal field theories, whose torus partition functions can be calculated as a perturbative series of the deformation parameter. We develop an efficient analytic method to calculate the perturbative series to very high orders, and determine its asymptotic behavior. We use the resurgence theory to uncover a nouveau type of non-perturbative corrections to the deformed torus partition function.
