Discriminating among interpretations for the $X(2900)$ states

Abstract

We make predictions for the production and decays of $X(2900)$ states, and their possible charged partners, in $B^{+}$ and $B^0$ decays, considering a number of competing models for the states, including triangle diagrams mediated by quark exchange or pion exchange, and resonance scenarios including molecules and tetraquarks. Assuming only isospin symmetry and the dominance of colour-favoured weak decays, we find characteristic differences in the predictions of the different models. Future experimental studies can therefore discriminate among the competing interpretations for the states.
