    A weak continuous beam of a CO2 laser was used to probe the time changing gain and absorption inside the cavity of a passive Q-switching CO2 laser with SF6 gas in an intracavity saturable absorber cell. The probe variations detected simultaneously with the laser intensity pulses gave experimental projection planes of the chaotic system attractor.55324632466Tachikawa, M., Hong, F.L., Tanii, K., Shimizu, T., (1988) Phys.

    Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

    A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results
