The ρ(ω)/B*(B) system and bound states in the unitary local Hidden Gauge approach

In this work, we study systems composed of a ρ/ω 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 ρB system, and a bound state with mass 5728 MeV and width around 20 MeV is obtained, which can be identified with the B1(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.
