Three charmonium-like states were studied using lattice QCD. The candidate for X(3872) was found slightly below DD* threshold in the channel with JPC=1++ and I=0, where cc as well as DD* and J/ψω interpolating operators were used. A charmonium-like channel with JPC=1+- and I=1 was also studied, as the recently discovered Zc+(3900) might reside there. Here J/ψπ and DD* scattering states were found, but no candidate for the Zc+(3900). We present also preliminary results for the JPC=0++ charmonium channel, where cc, DD and J/ψω interpolating operators were used. A candidate for a resonance, chic0^', that couples to DD in JPC=0++ was found.
