Zc(4025) as the hadronic molecule with hidden charm

We have studied the loosely bound D*(D) over bar* system. Our results indicate that the recently observed charged charmonium-like structure Z(c)(4025) can be an ideal D*(D) over bar* molecular state. We have also investigated its pionic, dipionic, and radiative decays. We stress that both the scalar isovector molecular partner Z(c0) and three isoscalar partners (Z) over tilde (c0,c1,c2) should also exist if Z(c)(4025) is a D*(D) over bar* molecular state in the framework of the one-pion-exchange model. Z(c0) can be searched for in the channel e(+)e(-) -> Y -> Z(c0)(4025)(pi pi)(P-wave) where Y can be Y(4260) or any other excited 1(--) charmonium or charmonium-like states such as Y(4360), Y(4660), etc. The isoscalar D*(D) over bar* molecular states (Z) over tilde (c0,c2) with 0(+)(0(++)) and 0(+)(2(++)) can be searched for in the three pion decay channel e(+)e(-) -> Y -> (Z) over tilde (c0,c2)(3 pi)(P-wave)(I=0). The isoscalar molecular state (Z) over tilde (c1) with 0(-)(1(+-)) can be searched for in the channel (Z) over tilde (c1)eta. Experimental discovery of these partner states will firmly establish the molecular picture.
