Abstract

In this work, we investigate the doubly bottom H(s)T(s) and H(s)T(s) systems by adopting the one-boson-exchange model, where H(s) and T(s) represent S-wave B(*)(s) and P-wave B(*)(s)1,2 doublets, respectively. For the HT systems, we predict some loosely bound states in the I(JPC)=0(1) BB1, I(JPC)=0(2) BB2*, I(JPC)=0(1) B^*B1 and I(JPC)=0(2) B^*B2* channels, which are the most promising hidden bottom molecular tetraquarks. For the HT systems, the B^*B1 channels with quantum numbers I(JP) = 0(1-), 0(2-) and the B^*B2^* channels with I(JP) = 0(2-) are also likely candidates for forming molecular tetraquarks. In contrast, no molecular candidates have been identified in the bottom-strange sectors. One can hope that our predictions will provide valuable insights to the LHCb and Belle II Collaborations as they continue to explore this fascinating field through experimental research.
