Lattice QCD simulations provide crucial information about the world sheet dynamics of confining strings (flux tubes). An accurate extraction of the world sheet S-matrix from lattice spectra requires accounting for polarization effects. Approximate integrability of the low energy world sheet theory makes it possible to apply the thermodynamic Bethe ansatz to incorporate polarization effects at all orders in the number of windings and at the leading order in the derivative expansion. However, a systematic application of this technique in the presence of nonintegrable effects and for multiparticle states becomes increasingly challenging. We point out that a recently understood equivalence between gravitational dressing and T¯T deformation provides a fully systematic and straightforward recipe to incorporate the leading polarization effects in the presence of an arbitrary inelasticity and for any number of particles. We illustrate this technique with several examples. [ABSTRACT FROM AUTHOR]
