Abstract
The Crystal Barrel detector has collected data on antiproton annihilation on Hydrogen and Deuterium at rest and at momenta up to 1940 MeV/c, accumulating a total of 600 M events with the goal of studying meson spectroscopy and searching for non- qq states. This large amount of data has allowed high statistics studies of exclusive final states produced under various initial conditions. Comparisons between different initial and final states greatly constrain the interpretation of these data sets. In particular, the requirement of consistency between fits of 3-body final state Dalitz plots is a powerful tool in the search for non-standard model resonances [1]. More recently, the study of the same Dalitz plot produced from antiproton annihilation on liquid and gaseous hydrogen, on deuterium or on liquid hydrogen at different center-of-mass energies has extended this approach to higher mass resonances.
