Recently, a study has shown that the Bose-Einstein condensates (BECs) formed by the d*(2380) hexaquarks (d*(2380)-BECs) can be thermally produced in the early universe and they are stable enough to be a competitive candidate for dark matter. Searching for the decaying signature of d*(2380)-BECs is a possible way to verify this dark matter model. In this article, we discuss the scattering and decaying properties of the d*(2380)-BECs and we show that the decay rate of the d*(2380)-BECs is correlated with the TeV cosmic-ray flux. The predicted average decay rate in our Galaxy is several orders of magnitude larger than the current observed upper limit. Therefore, it would be very difficult for us to search for the decaying signature of the d*(2380)-BEC dark matter model. Nevertheless, the size of the d*(2380)-BECs may be large enough to have self-interaction so that we can possibly detect them in the future.
