heavy mesons in heavy chiral unitary approachOriginal Research Article

In terms of the heavy chiral unitary approach, the View the MathML source, View the MathML source and View the MathML source resonances are discussed within the molecular state model. By examining the poles of the full unitary coupled-channel scattering amplitude on appropriate Riemann sheets, the former two states can be well reproduced, but not the third state. If one believes that the third state and first state are corresponding states in the non-strange and strange sectors, respectively, and they are all dominated by the molecular structure, there should exist one wide-width state at about 2.1 GeV and one narrow-width state at about 2.44 GeV, which are associated with the View the MathML source state. Meanwhile, we predict possible View the MathML source [View the MathML source] and View the MathML source [View the MathML source] states in the non-strange sector as the corresponding states of the strange View the MathML source [View the MathML source] ones.
