Three-body correlations in three-body exotic atoms are studied with simple models that consist of three bosons interacting through a superposition of long- and short-range potentials. We discuss the correlations among particles by comparing the energy shifts given by precise three-body calculations and by the Deser-Trueman formula, in which the long- and short-range contributions are factorized. By varying the coupling of the short-range potential, we evaluate the ranges of the strength where the two-body correlations dominate and where the three-body correlations cannot be neglected.

The authors study a mesonic atom system, with their accurate three-body calculation method. They have found that the calculated 3-body energy is in good agreement with the 2-body correlation model, DT model they call, for a weakly interacting regime, while the disagreement becomes significant for stronger interaction, in particular close to the unitary regime. Although their model is too simple to directly apply to the mesonic atom system they aim to study, their results have clear physical insights which may be useful for their forthcoming studies which should be more realistic. So I think the manuscript is ready for publication as it is.
