Abstract

Previous investigations of the three-body dynamics of BB mesons have shown that no Efimov effect arises in systems composed of three BB and BB^* mesons. This implies that the properties of such three-body systems can be described reliably within nonrelativistic effective field theory (NREFT) with short-range interactions using only two-body input, as three-body forces are strongly suppressed. In this work, we present leading-order predictions for the three-body point production rates of systems consisting of three BB and BB^* mesons. These predictions provide a novel way to experimentally probe the B()B^{(*)}-Bˉ()\bar{B}^{(*)} interactions, which play a crucial role in the hadronic-molecule interpretation of the Tbbˉ1(10610)T_{b\bar{b}1}(10610) and Tbbˉ1(10650)T_{b\bar{b}1}(10650) states. Moreover, they provide a way to test the approximate conformal symmetry predicted for such systems at low energies experimentally.
