New discussions of recent experimental results include Bose-Einstein condensation, dark matter and energy, neutrino mass, particle diffraction and interference, quarkonium, and molecular spectroscopy in the interstellar medium.
Another possibility is that a long lifetime might allow the formation of the quarkonium bound state b'-anti-b', which has its own specific decay modes, to bb-bar, gg, [gamma][gamma], and WW* [right arrow] vvll.
