Preliminary results from Fermilab E789

Description: Fermilab experiment 789 studies low-multiplicity decays of neutral D and B mesons in a high-rate fixed-target environment. Preliminary results from the 1991 run are presented.

Probing {anti u}/{anti d} asymmetry in the proton via quarkonium and W/Z production

Description: The experimented and theoretical status of the flavor dependence of the sea quark distributions in the proton is summarized. Sensitivities of {ital J}/{Psi}, {Gamma}, and {ital W/Z} production to the {ital {anti u}/{anti d}} asymmetry are then discussed.

Search for CP violation in charged-Xi and Lambda hyperon decays

Description: The authors have compared the p and {bar p} angular distributions in 117 million {Xi}{sup -} {yields} {Lambda}{pi}{sup -} {yields} p{pi}{sup -}{pi}{sup -} and 41 million {Xi}{sup +} {yields} {bar {Lambda}}{pi}{sup +} {yields} {bar p}{pi}{sup +}{pi}{sup +} decays using a subset of the data from the HyperCP experiment (ES71) at Fermilab. They find no evidence of CP violation, with the direct-CP-violating parameter A{sub {Xi}{Lambda}} {triple_bond} (a{sub {Xi}}a{sub {Lambda}} - {bar a}{sub {Xi}}{b… more
