We investigate the azimuthal anisotropy $v_2$ of particle production innucleus-nucleus collisions in the maximum entropy approach. This necessitatestwo new phenomenological input parameters $\delta$ and $\lambda_2$ comparedwith integrated multiplicity distributions. The parameter $\delta$ describesthe deformation of a flux tube and can be theoretically calculated in a bagmodel with a bag constant which depends on the density of surrounding fluxtubes. The parameter $\lambda_2$ defines the anisotropy of the particledistribution in momentum space and can be connected to $\delta$ via theuncertainty relation. In this framework we compute the anisotropy $v_2$ as afunction of centrality, transverse momentum and rapidity in qualitativeagreement with LHC data.
