“…In this short writeup I will summarize some of the different predictions for the 1 P 1 − 3 P cog splittings 1 . We will see that the recent CLEO [2] and E835 [3] measurements of the h c mass provide an important test of theoretical predictions. I will also briefly describe alternative ways of searching for the h c and h b [4] via radiative transitions [5] and in B-meson decays (for the h c ) [6,7,8,9].…”

“…An ideal experiment for studying some of the new cc mesons would be pp collisions at resonance. The effectiveness of resonant pp collisions for studying conventional charmonium states was demonstrated by the E760 and E835 experiments at Fermilab [11,12]. The "cc Mesons" section of the Review of Particle Physics [13] was largely rewritten by these experiments.…”

We present an estimate of the partial width of X(3872) into pp under the assumption that it is a weakly-bound hadronic molecule whose constituents are a superposition of the charm mesons D * 0D0 and D 0D * 0 . The pp partial width of X is therefore related to the cross section for pp → D * 0D0 near the threshold. That cross section at an energy well above the threshold is estimated by scaling the measured cross section for pp → K * − K + . It is extrapolated to the D * 0D0 threshold by taking into account the threshold resonance in the 1 ++ channel. The resulting prediction for the pp partial width of X(3872) is proportional to the square root of its binding energy. For the current central value of the binding energy, the estimated partial width into pp is comparable to that of the P-wave charmonium state χ c1 .

Donald Rumsfeld, in attempting to excuse the inexcusable, once (in)famously said that "there are things that we know we know; there are things that we know we don't know; and then there are things that we don't know that we don't know". Recent discoveries about hadrons with heavy flavours fall into those categories. It is of course the third category that is the most tantalising, but lessons from the first two may help resolve the third.
