Recently, the LHCb Collaboration reported their observation of the first two fully open-flavor tetraquark states named
(2900) and
(2900) with unknown parity. Inspired by the report, we consider all the possible four-quark candidates for X(2900), which include the molecular structure, diquark structure, and their coupling in a chiral quark model via the Gaussian expansion method. To identify the genuine resonances, the real-scaling method (stabilization method) was employed. Our results show that five possible resonances,
with
MeV,
with
MeV,
with
MeV,
with
MeV, and
with
MeV, originate in the
system. Compared with experimental data,
with
MeV may be an optimal
candidate. However, none of the resonances have a similar width for
. Hence, further study is required.
