    The associations between risk-taking, hopelessness, and reasons for living were explored in a sample of 312 Italian students. Respondents completed the Physical Risk Assessment Inventory, the Physical Risk-Taking Behavior Inventory, the Beck Hopelessness Scale, and the Reasons for Living Inventory. Students with lower scores on the Reasons for Living Inventory and higher scores on the Beck Hopelessness Scale rated the risky activities as less risky and engaged in them more often. Women obtained higher scores on risk assessment, lower scores on personal risk-taking and higher scores on the Reasons for Living Inventory and most of its subscales. Men in general and people who take risks and perceive lower risk are more hopeless and relatively weak in reasons for living

    We present results from an analysis of B0(B¯¯¯0)→ρ+ρ− using 232×106 Υ(4S)→BB¯¯¯ decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We measure the longitudinal polarization fraction fL=0.978±0.014(stat)+0.021−0.029(syst) and the CP-violating parameters SL=−0.33±0.24(stat)+0.08−0.14(syst) and CL=−0.03±0.18(stat)±0.09(syst). Using an isospin analysis of B→ρρ decays, we determine the unitarity triangle parameter α. The solution compatible with the standard model is α=(100±13)°

    We present results from an analysis of B0(B̅ 0)→ρ+ρ- using 232×106 Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We measure the longitudinal polarization fraction fL=0.978±0.014(stat)+0.021/-0.029(syst) and the CP-violating parameters SL=-0.33±0.24(stat)+0.08/-0.14(syst) and CL=-0.03±0.18(stat)±0.09(syst).

    Search for strange-pentaquark production in e+e− annihilation at √s=10.58 GeV

    No full text
    We search for strange pentaquark states that have been previously reported by other experiments -- the Θ(1540)+, Ξ5(1860)−−, and Ξ5(1860)0 -- in 123 fb−1 of data recorded with the BaBar detector at the PEP-II e+e− storage ring. We find no evidence for these states and set 95% confidence level upper limits on the number of Θ(1540)+ and Ξ5(1860)−− pentaquarks produced per e+e− annihilation event that are about eight and four times lower than the rates measured for ordinary baryons of similar mass

    Measurements of branching fractions and time-dependent CP-violating asymmetries in B→η'K decays

    No full text
    We present measurements of the B -> eta' K branching fractions:for B+ -> eta' K+ we measure also the time-integrated charge asymmetry Ach, and for B0 -> eta' K0S the time dependent CP-violation parameters S and C. The data sample corresponds to 232 million B Bbar pairs produced by e+ e- annihilation at the Upsilon(4S). The results are BF(B+ -> eta' K+) = (68.9 +- 2.0 +- 3.2) * 10^-6, BF(B0 -> eta' K0) = (67.4 +- 3.3 +- 3.2) * 10^-6, Ach = 0.033 +- 0.028 +- 0.005, S=0.30 +- 0.14 +- 0.02, C=-0.21 +- 0.10 +- 0.02, where the first error is statistical and the second systematic

    Measurement of branching fractions and charge asymmetries for exclusive B decays to charmonium

    No full text
    We report measurements of branching fractions and charge asymmetries of exclusive decays of neutral and charged B mesons into two-body final states containing a charmonium state and a light strange meson. The charmonium mesons considered are J/ψ, ψ(2S) and χc1, and the light meson is either K or K∗. We use a sample of about 124×106 BB¯¯¯ pairs collected with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center
