      Evidence for light by light scattering and search for axion like particle in ultraperipheral PbPb collisions 1h

      Abstract
      Light by light (LbyL) scattering is a very rare phenomena which proceeds, at leading order in
      the fine structure constant, via virtual box diagrams involving electrically charged fermions
      (leptons and quarks) or W bosons. The evidence for light by light scattering is provided
      by exploiting the strong electromagnetic fields from ultraperipheral PbPb collisions. This
      process has been proposed as a sensitive channel to study physics beyond the standard model
      as the modifications of the LbyL scattering rates can occur if new heavy particles such as
      magnetic monopoles, vector-like fermions or axion-like particles contribute. These searches
      require the accurate estimation of the heavy ion (PbPb) data luminosity. This talk covers the
      results of evidence for light by light scattering and emittance scan analysis of PbPb collisions
      for luminosity measurement.
