Study of heavy quark conserving weak decays in the quark model
Peng-Yu Niu, Qian Wang, Qiang Zhao
Within the framework of a constituent quark model, we investigate the heavy quark conserving weak decays of and . This process involves elementary transitions of $us\to…
Coupled-channel approach to including three-body effects
Meng-Lin Du, Vadim Baru, Xiang-Kun Dong +6
A coupled-channel approach is applied to the charged tetraquark state recently discovered by the LHCb Collaboration. The parameters of the interaction are fixed by a fit…
Effective range expansion for narrow near-threshold resonances
Vadim Baru, Xiang-Kun Dong, Meng-Lin Du +6
We discuss some general features of the effective range expansion, the content of its parameters with respect to the nature of the pertinent near-threshold states and the necessary…
Prompt production of the hidden charm pentaquarks in the LHC
Pan Ling, Xiao-Hu Dai, Meng-Lin Du +1
Motivated by the observation of the first hidden charm pentaquarks by the LHCb collaboration in 2015 and the updated analysis with an order-of-magnitude larger data set in 2019, we…
Possible studies at the first stage of the NICA collider operation with polarized and unpolarized proton and deuteron beams
V. V. Abramov, A. Aleshko, V. A. Baskov +32
This paper contains suggestions for experiments with usage of the Spin Physics Detector (SPD) at the first stage of the SPD NICA Programme developing at JINR. Double polarized pp-,…
Revisiting the nature of the pentaquarks
Meng-Lin Du, Vadim Baru, Feng-Kun Guo +4
The nature of the three narrow states, i.e., , and , is under intense discussion since their discovery from the updated analysis by LHCb. In…
