Isospin analysis of BâDâD¯K and the absence of the Zc(3900) in B decays
We study the isospin amplitudes in the exclusive B to DâD¯K decay process and fit the available Dâ0D¯0 invariant mass distributions near threshold. The analysis demonstrates that the production of the isospin triplet DâD¯ state is highly suppressed compared to the isospin singlet one. That explai...
