Molecular picture for X0(2900) and X1(2900)

Jun He et al.

Summary: Inspired by the newly observed X-0(2900) and X-1(2900) states at LHCb, this study investigates the K*(D) over bar* and K (D) over bar (1) interactions, predicting bound and virtual states which can be related to the observed X-0(2900) and X-1(2900). The results suggest the existence of additional states that can be searched for in future experiments.

Mass spectrum and strong decays of tetraquark csqq states

Guang-Juan Wang et al.

Summary: The mass spectrum and strong decays of S-wave csqq states in the compact tetraquark scenario were systematically studied. The recently observed X0(2900) might be a good candidate for a tetraquark state, while future experimental search for X(2649) will be helpful.

Summary: Motivated by the recent discovery of exotic states X-0(2900) and X-1(2900) by the LHCb collaboration, this study investigates possible interpretations of these states through QCD sum rules method. Results show that the mass calculations align well with experimental observations.

Kinematical cusp and resonance interpretations of the X(2900)

T. J. Burns et al.

Summary: This study investigates the interpretation of the LHCb vector udc over bar s over bar state X(2900) as a kinematical cusp effect from (D)*K* and (D-1)*K(*) interactions. A satisfactory fit to the Dalitz plot projection is achieved using a triangle diagram model with hadronic final state interactions. The evidence for the generation of resonances due to strong enough final state interactions is inconclusive, but provides a somewhat better fit.

Observation of new excited Bs0 states

R. Aaij et al.

Summary: A structure observed in the B +/- K -/+ mass spectrum from proton-proton collisions is interpreted as overlapping excited Bs0 states. A two-peak hypothesis better describes the data than a single resonance, and the ratio of the new states' production cross-section times branching fraction relative to the previously observed Bs20 state is determined to be 0.87 +/- 0.15(stat)+/- 0.19(syst).

New scalar resonance X0(2900) as a (D)over-bar*K* molecule: mass and width

S. S. Agaev et al.

Summary: This study explores the features of the scalar structure X-0(2900) and treats it as a hadronic molecule composed of conventional mesons. The mass, coupling, and width of X-0(2900) are calculated using QCD two-point sum rule method. The predictions for the mass and width of the hadronic molecule support the molecule interpretation of X-0(2900).

Study of the decays of S-wave (D)over-bar*K* hadronic molecules: The scalar X0(2900) and its spin partners (X)over-tildeJ(J=1,2)

Cheng-Jian Xiao et al.

Summary: In this study, the decays of the observed fully open-flavor tetraquark state X-0(2900) were investigated using an effective Lagrangian approach. The estimated partial widths of X-0(2900) aligned with experimental observations, and predictions were made for the decay behaviors of unobserved states. The results suggest that future experiments searching for these unobserved states may contribute to understanding the nature of X-0(2900).
