New a(1)(1420) state: structure, mass, and width
(American Physical Society, 2018-03)
The structure, spectroscopic parameters and width of the resonance with quantum numbers J(PC) = 1(++) discovered by the COMPASS Collaboration and classified as the a(1)(1420) meson are examined in the context of QCD sum ...
Strong decay of P-c (4380) pentaquark in a molecular picture
There are different assumptions on the substructure of the pentaquarks P-c(4380) and P-c(4450), newly founded in J/psi N invariant mass by the LHCb Collaboration, giving consistent mass results with the experimental ...
