Abstract
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.
