epsilon-prime / epsilon: Review and recent progress
The evolution of the theoretical perspective on {epsilon}{prime}/{epsilon} is reviewed. The introduction of the Z{sup O} penguin and the effects of high M{sub t} are discussed, in particular the possibility for {epsilon}{prime}/{epsilon} to be identically zero. Recent calculations of {epsilon}{prime}/{epsilon} based on current estimates and bounds on the input parameters are presented. 41 refs., 13 figs.

Fine structure of the P states in heavy quarkonium and the nature of the spin-dependent potential
Abstract We discuss the failure of existing theories to agree with the experimental measurements of the fine structure of the χ states of the b b and c c systems. We rule out various possible explanations, such as mixing of the 2P triplet with the 1F triplet. We use thefact that the spin-independent potential is well-determined in the relevant range to extract accurate determinations of expectation values of the spin-dependent potentials providing tests for future theories. We find that the usual ansatz that the q q interaction has effective vector and scalar contributions only is very unlikely to be sufficient to explain the fine structure of the 3 P levels and to accomodate the recent measurement of the mass of the 1 P state in charmounium.

Annihilations of Antiprotons at Rest in Hydrogen. V. Multipion Annihilations
Approximately 45 000 pionic annihilations of stopped antiprotons in hydrogen have been measured and analyzed. The relative annihilation rates into the various multipion final states are presented. The experimental distributions of the invariant masses of all the possible pion combinations have been obtained. Strong production of the $\ensuremath{\rho}$, $\ensuremath{\omega}$, and $\ensuremath{\eta}$ meson has been observed, and their production rates have been established. The rates for simultaneous production of ${\ensuremath{\rho}}^{0}{\ensuremath{\rho}}^{0}$, ${\ensuremath{\rho}}^{0}{\ensuremath{\omega}}^{0}$, and ${\ensuremath{\rho}}^{0}{\ensuremath{\eta}}^{0}$ are discussed.
