The $ρ(ω)B^*(B)$ interaction and states of $J=0,1,2$ (1507.06787v1)
Published 24 Jul 2015 in hep-ph
Abstract: In this work, we study systems composed of a $\rho/\omega$ and $B*$ meson pair. We find three bound states in isospin, spin-parity channels $(1/2, 0+)$, $(1/2, 1+)$ and $(1/2, 2+)$. The state with $J=2$ can be a good candidate for the $B_2*(5747)$. We also study the $\rho B$ system, and a bound state with mass $5728$ MeV and width around $20$ MeV is obtained, which can be identified with the $B_1(5721)$ resonance. In the case of $I=3/2$, one obtains repulsion and thus, no exotic (molecular) mesons in this sector are generated in the approach.
