The past decades witnessed the golden era of hadron physics. Many excited open heavy
flavor mesons and baryons have been observed since 2017. We shall provide an updated …

We study strong decays of the possible fully-charm tetraquarks recently observed by LHCb,
and calculate their relative branching ratios through the Fierz rearrangement. Together with …

We conduct systematic calculations of the S-wave fully strange systems with “normal”(JPC=
0++, 1+-, 2++) and “exotic”(JPC= 0+-, 1++, 2+-) C-parities, which are the strange analog of …

Born cross sections for the processes e+ e−→ ω η and e+ e−→ ω π 0 have been determined
for center-of-mass energies between 2.00 and 3.08 GeV with the BESIII detector at the …

The process e+ e-→ ϕ η is studied at 22 center-of-mass energy points (s) between 2.00 and
3.08 GeV using 715 pb-1 of data collected with the BESIII detector. The measured Born …

We apply the QCD sum rule method to systematically study the S-and P-wave fully strange
tetraquark states within the diquark-antidiquark picture. We systematically construct their …

In this work, we construct 36 tetraquark configurations for the 1 S-, 1 P-, and 2 S-wave states,
and make a prediction of the mass spectrum for the tetraquark sss¯ s¯ system in the …

We study the fully strange tetraquark states with the exotic quantum numbers JPC= 0+-and
2+-. We construct their corresponding diquark-antidiquark interpolating currents and apply …

A bstract A partial wave analysis on the process e+ e−→ ωπ+ π− is performed using 647
pb− 1 of data sample collected by using the BESIII detector operating at the BEPCII storage …

We apply the QCD sum rule method to systematically study the fully strange tetraquark
states with the quantum number J PC= 2++. We construct both the diquark–antidiquark and …
