The ρ(ω)B∗(B) interaction and states of J=0,1,2

subject

description

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 B2∗(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.
