Schroedinger cats, quantum slings and azimuthal effects in   nucleus-nucleus collisions
  Confinement of a chromodynamical string can result in specific effects in scattering processes and multiparticle production. In particular, due to its rotation secondary fragments of the splitting apart string can move like stones thrown from a sling. That would be detected as the azimuthal asymmetry of particle distributions in individual events. Thus we propose to explain the elliptic flow observed in AA-collisions as a sling-effect. It can provide information about confinement of quarks inside particles or binding forces in nuclei. Nonclassical states of the created particles like the Schroedinger cats are produced. Some classical and quantum-mechanical estimates of possible effects are given. Experimental facts which can be used for their verification are discussed.
