Short-range production of three bottom mesons

A bstract Previous investigations of the three-body dynamics of B mesons have shown that no Efimov effect arises in systems composed of three B and B * 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 B and B * mesons. These predictions provide a novel way to experimentally probe the $$ {B}^{\left(\ast \right)}-{\overline{B}}^{\left(\ast \right)} $$ B ∗ − B ¯ ∗ interactions, which play a crucial role in the hadronic-molecule interpretation of the $$ {T}_{b\overline{b}1}(10610) $$ T b b ¯ 1 10610 and $$ {T}_{b\overline{b}1}(10650) $$ T b b ¯ 1 10650 states. Moreover, they provide a way to test the approximate conformal symmetry predicted for such systems at low energies experimentally.
