Predictions of super-exotic heavy mesons from $K^{*}B^{*}B^{*}$ interactions

TL;DR

This paper theoretically predicts the existence of super-exotic heavy meson bound states involving strange and double-bottom flavors using a three-body interaction model based on the fixed center approach.

Contribution

It introduces a novel three-body interaction analysis for ${ar K^*}{ar B^*}{ar B^*}$ systems, predicting bound states with specific quantum numbers.

Findings

Bound states found for all considered channels with J=0, 1, 2

States have isospin 1/2 and negative parity

Results suggest possible new exotic mesonic resonances.

Abstract

We make a theoretical study of the three-body system composed of ${\bar K^*}{\bar B^*}{\bar B^*}$ to look for possible bound states, which could be associated to mesonic resonances of very exotic nature, containing open strange and double-bottom flavours. The three-body interaction is evaluated by using the fixed center approach to the Faddeev equations where the ${\bar B^*}{\bar B^*}$ is bound forming an $I(J^P)=0(1^+)$ state, as it was found in previous works, and the third particle, the ${\bar B^*}$, of much smaller mass, interacts with the components of the cluster. We obtain bound states for all the channels considered: spin $J=0$, 1 and 2, all of them with isospin $I=1/2$ and negative parity.
