“…The purpose of this brief note is that of emphasizing the usefulness of such realization by explicitly showing how the free field approach can be used to compute three-point scattering amplitudes in AdS 3 . It is known that the free field approach and the Coulomb gas-like prescription were previously employed to this end [3]; however, the computation here regards those cases that were not worked out in previous free field calculations. Our attention will be focussed on the three-point functions that violate the winding number conservations.…”

Three-point correlation function in perturbed conformal field theory coupled to twodimensional quantum gravity (perturbed Liouville gravity) is explicitly computed by using the free field approach. The representation considered here is the one recently proposed in [1] to describe the string theory in AdS 3 space. Consequently, this computation extends previous results which presented free field calculations of particular cases of string amplitudes, and confirms that the free field approach leads to the exact result. Remarkably, this representation allows to compute winding violating three-point functions without making use of the spectral flow operator. Exact agreement is obtained with previous computations of these observables, which were done by following different formalisms.
