    Might be a little too early in the morning. This guy is just a resonance of D_s+, which has a mass of 1968 MeV, and also is made up of c & s_bar. Naked charm just means the particle has a c and no c_bar, which is perfectly fine. Charmed particles have been around for a while now.

    The combination was not the surprise, but the missing mass is, which suggests that the theoretical calculation of the binding force is incorrect (though such calculation is often an approximation themself) This usually signals that some aspect of the theory on the force is wrong or that their is yet another particle that was undetected, thus robbing some mass away. (Neutrino was 'discovered' this way)
