Abstract:

The cross section σe+e- → J/ψX = 2.52 ± 0.21 ± 0.21 pb was measured. Restricting to p* > 2 GeV/c, 1.87 ± 0.10 ± 0.15 pb were found. The total cross section and the angular distribution favor the NRQCD calculation over the color singlet model.

Abstract:

Three-jet production in the reaction ep → eXp has been studied with the ZEUS detector at HERA using an integrated luminosity of 42.74 pb^-1.The data were measured in the kinematic region 5 < Q² < 100 GeV², 200 < W < 250 GeV and 23 < MX < 40 GeV. The diffractive signal was selected by requiring a large rapidity gap in the outgoing proton direction. Jets were reconstructed in the centre-of-mass system of X using the exclusive kT-algorithm. A sample of three-jet events in diffraction has been identified. Differential cross sections were measured as a function of the jet pseudorapidity and jet transverse momentum with respect to the virtual photon-pomeron axis. The jets going in the pomeron direction are broader than those going in the virtual-photon direction. This is consistent with models predicting that gluons are predominantly produced in the pomeron direction and quarks in the virtual-photon direction. © 2001 Elsevier Science B.V.

Abstract:

We present an updated measurement of time-dependent CP-violating asymmetries in neutral B decays with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. This result uses an additional sample of γ(4S)decays collected in 2001, bringing the data available to 32 ×10⁶ BB^¯ We select events in which one neutral B meson is fully reconstructed in a final state containing charmonium and the flavor of the other neutral B meson is determined from its decay products. The amplitude of the CP-violating asymmetry, which in the standard model is proportional to sin2β, is derived from the decay time distributions in such events. The result sin2β=0.59 ± 0.14(stat)±0.05(syst) establishes CP violation in the B⁰ meson system. We also determine |λ|= 0.93±0.09(stat)±0.03(syst), consistent with no direct CP violation. © 2001 The American Physical Society.
