Abstract
In the present work, we perform a coupled-channel analysis of B(s)(*)B¯(s)(*) systems with the one-boson-exchange potentials. We first study the I(JPC)=1(1+−) BB¯*/B*B¯* system to describe the Zb(10610) and Zb(10650) particles as molecular states and determine the reasonable range of cutoff parameter Λ. Then, other B(s)(*)B¯(s)(*) combinations with different quantum numbers are systematically investigated. Some bound states and resonances appear in the isoscalar systems, while only several shallow bound states exist for isovector systems. Far away from the excited conventional P-wave bottomium, these predicted states can be easily identified as exotic particles both theoretically and experimentally. Moreover, the ηb(nS)/ϒ(nS) plus light mesons are the excellent final states to search for the bound states, while the BB¯*+H.c. and B*B¯* channels are suitable for the resonances. We highly recommend that the LHCb and Belle II Collaborations hunt for these bottomoniumlike states in the future. Published by the American Physical Society 2024
