Query: Two-dimensional discrete wavelet analysis of multiparticle event
  topology in heavy ion collisions   The event-by-event analysis of multiparticle production in high energy hadron
and nuclei collisions can be performed using the discrete wavelet
transformation. The ring-like and jet-like structures in two-dimensional
angular histograms are well extracted by wavelet analysis. For the first time
the method is applied to the jet-like events with background simulated by event
generators, which are developed to describe nucleus-nucleus collisions at LHC
energies. The jet positions are located quite well by the discrete wavelet
transformation of angular particle distribution even in presence of strong
background.
