Abstract

In this work, we investigate the decays of the fully open-flavor tetraquark state X0(2900) which was observed by the LHCb collaboration very recently. By using an effective Lagrangian approach, the partial widths of X0(2900) are estimated, where X0(2900) is assumed to be an S-wave D¯*K* hadronic molecule with I=0. It is found that the estimated results are in agreement with the experimental observations. Moreover, we also predict the decay behaviors of the other unobserved X˜J(J=1,2), which are the spin partners of the X0(2900) in the S-wave D¯*K* picture. It is pointed out that the X˜1 state with I=0 is a broad state with the width more than 100 MeV, while another X˜2 state with I=0 is a narrow state with the width approaching half of that for the X0(2900). In addition, our results also show that the D¯*K mode is expected to be the dominant decay mode for both X˜1 and X˜2. Searching for those unobserved X˜J(J=1,2) in the future experiments might be helpful to understand the nature of X0(2900).
