The observation of the exotic states ${X}_{0,1}(2900)$ with four open flavors by LHCb Collaboration has promoted great interest in searching for open-charm and open-bottom tetraquark states. In this work, we perform a systematic study open-heavy systems $qq\overline{q}\overline{Q}$ ($q=u$, $d$, $s$ $Q=c$, $b$) within improved chromomagnetic interaction model. mass spectra color-spin wave functi...

Abstract After the experimental observation of charged and neutral $$Z_c(3900)$$ Z c ( 3900 ) , it is prime importance to pursue searches for additional production modes these exotic states. In th...

During recent years, the study of exotic hadrons including tetraquarks and pentaquarks has attracted a lot interest, more studies are in progress experimentally theoretically. It is well known that at sufficiently large transverse momentum dominant production mechanism for standard heavy (mesons/baryons) actually fragmentation so same also proposed hadrons. This work first attempt to direct qua...
