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

preprint2015arXivOpen access

Abstract

In this work, we study systems composed of a ρ/ωρ/ω and B∗B^* meson pair. We find three bound states in isospin, spin-parity channels (1/2,0+)(1/2, 0^+), (1/2,1+)(1/2, 1^+) and (1/2,2+)(1/2, 2^+). The state with J=2J=2 can be a good candidate for the B2∗(5747)B_2^*(5747). We also study the ρBρB system, and a bound state with mass 57285728 MeV and width around 2020 MeV is obtained, which can be identified with the B1(5721)B_1(5721) resonance. In the case of I=3/2I=3/2, one obtains repulsion and thus, no exotic (molecular) mesons in this sector are generated in the approach.
