Molecular charmonium. A new spectroscopy?

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

description Using a constituent quark model, we study the mass and decay channels of meson meson and mesonbaryon structures in the charm sector.We show that the X(3872) and the X(3940) resonances can be described as mixed charmonium-molecular states withJPC = 1++, whereas the X(3915) and the Y(3940) can be assigned to similar mixed states withJPC = 0++.In the baryonspectrum we identify theΛc+(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−.
