Puzzles in hyperon, charm and beauty physics

Puzzles awaiting better experiments and better theory include: (1) the contradiction between good and bad SU(3) baryon wave functions in fitting Cabibbo theory for hyperon decays, strangeness suppression in the sea and the violation of the Gottfried Sum rule - no model fits all; (2) Anomalously enhanced Cabibbo-suppressed D+ --> K*+(sd) decays; (3) anomalously enhanced and suppressed B --> eta'/X decays; (4) the OZI rule in weak decays; (5) Vector dominance (W --> pi, rho, a(1), D-s, D-s(*)) in weak decays (6) Puzzles in doubly-cabibbo-suppressed charm decays. (7) Problems in obtaining Lambda spin structure from polarization measurements of produced Lambda's.
