OK, this is just getting ridiculous

Belle claims to see a “Z(4430)” as a π±ψ’ structure in B → Kπ±ψ’ decays. This joins the X(3872), Y(3940), Y(4260), Y(4350), and Y(4660) in the zoo of incomprehensible things above DD threshold that decay to charmonia. Unlike the other objects, this one is charged, which means it can’t be a hybrid or conventional charmonium state.
