Motivated by recent theoretical predictions about the existence of a B B bound state (also denoted as X(10550) ), in this work we estimate the production of the S-wave B+ B- molecule via Υ(4S) radiative decays. In particular, we make use of effective Lagrangian approach and the compositeness condition to calculate the X(10550) production rate via Υ(4S)→ γX(10550) decays employing triangle diagrams. Our results show that the partial decay width of this reaction is of the order of 0.5 - 192 \keV for a respective binding energy of 1 - 100 MeV, corresponding to a branching fraction of 10-5 - 10-3. These findings suggest that the existence of the X(10550) might be checked via the analysis of the mentioned decay in present and future experiments.
