Molecular charmonium. A new spectroscopy?

Using a constituent quark model, we study the mass and decay channels of meson meson and meson baryon structures in the charm sector.We show that the X(3872) and the X(3940) resonances can be described as mixed charmonium-molecular states with JPC = 1++, whereas the X(3915) and the Y(3940) can be as...

Zusammenfassung:Using a constituent quark model, we study the mass and decay channels of meson meson and meson baryon structures in the charm sector.We show that the X(3872) and the X(3940) resonances can be described as mixed charmonium-molecular states with JPC = 1++, whereas the X(3915) and the Y(3940) can be assigned to similar mixed states with JPC = 0++.In the baryon spectrum we identify the Λc+(2940) as a D*N molecule with (I)JP = (0)3/2− and the recently reported Xc(3250) as a D*Δ resonance with (I)JP = (2)1/2−.
