STRESS AND CHILDHOOD
In this work the complexity of educational and rehabilitation interventions in different conditions of stress in childhood were underlined. The role played by educative agencies and different professionals, especially Educators, was indicated. The need for an integrated and coordinate intervention was stressed.
Measurement of W ± Z production in proton-proton collisions at √s =7 TeV with the ATLAS detector
A study of W±Z production in proton-proton collisions at √s=7 TeV is presented using data corresponding to an integrated luminosity of 4.6 fb−1 collected with the ATLAS detector at the Large Hadron Collider in 2011. In total, 317 candidates, with a background expectation of 68±10 events, are observed in double-leptonic decay final states with electrons, muons and missing transverse momentum. The total cross-section is determined to be σtotWZ=19.0+1.4−1.3(stat.)±0.9(syst.)±0.4(lumi.) pb, consistent with the Standard Model expectation of 17.6+1.1−1.0 pb. Limits on anomalous triple gauge boson couplings are derived using the transverse momentum spectrum of Z bosons in the selected events. The …
