Abstract A novel approach is proposed to probe the nature of the double charm tetraquark through the prompt production asymmetry between $$T_{\bar{c}\bar{c}}^-$$ T c ¯ c ¯ - and $$T_{cc}^+$$ T cc + in pp collisions. When comparing two theoretical p

Abstract We extend our previous study of the interactions of $$\bar{D}^{(*)} \Lambda _c - \bar{D}^{(*)}\Sigma _c^{(*)}$$ D ¯ ( ∗ ) Λ c - D ¯ ( ∗ ) Σ c ( ∗ ) within an analytic, unitary, coupled-channel approach by including the $$J/\psi p$$

The primary objective of this study is to investigate hadronic molecules of K⁎K¯1(1270) using a one-boson-exchange model, which incorporates exchanges of vector and pseudoscalar mesons in the t-channel, as well as the pion exchange in the u-channe

Abstract We extend the chiral quark model for u, d, c and b quarks with vector mesons, which we proposed in the previous analysis, to a model with the s quark. We include the nonet pseudo-scalar and vector mesons together with the singlet scalar meso

Abstract In hadron spectrum physics, the partial wave analysis is a primary method used to extract properties of hadronic resonances. The covariant orbital-spin coupling scheme holds unique advantages over other partial wave methods due to its Lorent

Abstract We study dynamically generated $$a_0$$ a 0 resonances by interactions between vector mesons including their coupling to channels of pseudoscalar mesons within coupled-channel approach. Both vector and pseudoscalar mesons are considered as t-

Abstract The interactions of $${\bar{D}}^{(*)} \Lambda _c - {\bar{D}}^{(*)}\Sigma _c^{(*)}$$ D ¯ ( ∗ ) Λ c - D ¯ ( ∗ ) Σ c ( ∗ ) are studied within the framework of a dynamical coupled-channel approach. A series of bound states and resonanc

We have a look at the Pcs states generated from the interaction of D¯(⁎)Ξc(′⁎) coupled channels. We consider the blocks of pseudoscalar-baryon (12+,32+) and vector-baryon (12+,32+), and find 10 resonant states coupling mostly to D¯Ξc,D¯⁎

In this work, we interpret the newly observed η1(1855) resonance with exotic JPC=1−+ quantum numbers in the I=0 sector, reported by the BESIII Collaboration, as a dynamically generated state from the interaction between the lightest pseudoscalar m

Abstract We discuss the possible existence of the fully-heavy tetraquarks. We calculate the ground-state energy of the $$bb {\bar{b}} {\bar{b}}$$ bbb¯b¯ bound state, where b stands for the bottom quark, in a nonrelativistic effective field theory f
