Abstract
Recently three experiments reported a discovery of manifestly exotic Zc+(3900) in the decay to J/ÏÏ+, while J and P are experimentally unknown. We search for this state on the lattice by simulating the channel with JPC=1+â and I=1, and we do not find a candidate for Zc+(3900). Instead, we only find discrete scattering states DD¯â and J/ÏÏ, which inevitably have to be present in a dynamical QCD. The possible reasons for not finding Zc+ may be that its quantum numbers are not 1+â or that the employed interpolating fields are not diverse enough. Simulations with additional types of interpolators will be needed to reach a more definite conclusion.
