Exclusive semileptonic $B$ decays to the ground and excited states of light mesons

V. O. Galkin, Xian-Wei Kang

Exclusive semileptonic decays of $B$ mesons to the ground, radially and orbitally excited states of light mesons are investigated in the framework of the relativistic quark model b…

Composite nature of exotic states from data analysis

Xian-Wei Kang

We introduce two basic concepts: the compositeness for resonance and the Castillejo-Dalitz-Dyson (CDD) pole. Applying them to hadron states $X (3872)$ , $Z_{b} (10610)$ and $Z_{b} (10650)$ …
