By using a (string inspired) low energy effective field theory with a massive dilaton and a coupling function to gauge fields to model quark confinement, we show that the experimental data of charmonium and bottomonium is fitted when the dilaton mass is given a value about 57 MeV. Our estimate lies in the range proposed by other works which present the dilaton as a dark matter candidate.
