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.
