Abstract

In this work, we study the -type molecular systems systematically via the one pion exchange model, where T denotes the narrow meson or meson and is its antiparticle. With the effective potentials, we try to find the bound-state solutions of the corresponding systems, which provide crucial information of whether -type molecular states exist. By our analysis, we predict some -type molecular states which may be accessible at future experiments like LHCb and forthcoming BelleII.
