摘要: In this work, we study the $T\bar{T}$-type molecular systems systematically via one pion exchange model, where $T$ denotes narrow $J^P=1^+$ $D_1$ meson or $2^+$ $D_2^*$ and $\bar{T}$ is its antiparticle. With effective potentials, try to find bound state solutions of corresponding systems, which provide crucial information whether there exist states. According our analysis, predict some states may be accessible at future experiments like LHCb forthcoming BelleII.
