Possible heavy molecular states composed of a pair of excited charm-strange mesons

摘要 The P-wave charm-strange mesons Ds0（2317） and Ds1（2460） lie below the DK and D＊K threshold respectively. They are extremely narrow because their strong decays violate the isospin symmetry. We study the possible heavy molecular states composed of a pair of excited charm strange mesons. As a byproduct, we also present the numerical results for the bottonium-like analogue.
