abstract="In analogy to the f(0)(500), which appears as a pi pi resonance in chiral unitary theory, and the f(0)(980), which appears as a quasibound K (K) over bar state, the extension of this approach to the charm sector also predicts a quasibound D (D) over bar state with mass around 3720 MeV, named as X(3700), for which some experimental support is seen in the e(+)e(-) -> J/psi D (D) over bar reaction close to the D (D) over bar threshold. In the present work we propose three different experiments to observe it as a clear peak. The first one is the radiative decay of the psi(3770), psi(3770) -> gamma X(3700) -> gamma eta eta{\textquoteright}. The second one proposes the analogous reaction psi(4040) -> gamma X(3700) -> gamma eta eta{\textquoteright} and the third reaction is the e(+)e(-) -> J/psi X(3700) -> J/psi eta eta{\textquoteright}. Neat peaks are predicted for all the reactions and the calculated rates are found within measurable range in present facilities.",
