In recent years, more and more exotic hadronic states have been discovered successively. Many of them can be explained as hadronic molecules, such as $D_{s0}^*(2317)$, $X(3872)$, and $P_c$ pentaquark states. Analogous to the formation of nuclei, we study three-body hadronic molecules with the Gaussian expansion method and predict the existence of the $DDK$, $Xi_{cc}Xi_{cc}bar{K}$, and $BBbar{K}$ bound states, which are likely to be found in the current and updated facilities.
We investigate the mass spectrum and electromagnetic processes of charmonium system with the nonperturbative treatment for the spin-dependent potentials, comparing the pure scalar and scalar-vector mixing linear confining potentials. It is revealed t
Many charmonium-like and bottomonium-like $XYZ$ resonances have been observed by the Belle, Babar, CLEO and BESIII collaborations in the past decade. They are difficult to fit in the conventional quark model and thus are considered as candidates of e
We investigate the potential of the channel {em mono-Higgs + MET} in yielding signals of dark mater at the high-luminosity Large Hadron Collider (LHC). As illustration, a scalar dark matter in a Higgs portal scenario has been chosen, whose phenomenol
A symmetry-preserving treatment of a vector$times$vector contact interaction is used to compute spectra of ground-state $J^P = 0^pm, 1^pm$ $(fbar g)$ mesons, their partner diquark correlations, and $J^P=1/2^pm, 3/2^pm$ $(fgh)$ baryons, where $f,g,h i
In this paper we prove a new optimal bound on the logarithmic slope of the elastic slope when: elastic cross section and differential cross sections in forward and backward directions are known from experimental data. The results on the experimental
