DESCRIPTION:The scattering of electroweak gauge bosons is closely connecte
 d to the electroweak gauge symmetry and its spontaneous breaking through t
 he Higgs mechanism. It allows to probe the self-interaction of electroweak
  gauge bosons\, in particular their quartic vertices. The contribution of 
 the Higgs boson to the weak boson scattering amplitude ensures unitarity o
 f the scattering matrix. Therefore\, the scattering of massive electroweak
  gauge bosons is sensitive to deviations from the Standard Model prescript
 ion of the electroweak interaction and of the properties of the Higgs mech
 anism.\nAt the Large Hadron Collider\, the scattering of massive electrowe
 ak gauge bosons is accessible\nthrough the measurement of purely electrowe
 ak production of two jets and two gauge bosons. This talk presents the fir
 st measurement of electroweak production of two jets and two identically c
 harged W bosons\, which yields the first observation of a process with con
 tributions from quartic gauge interactions of massive electroweak gauge bo
 sons.\nLimits on anomalous quartic gauge couplings as described within the
  framework of an effective field theory are derived based on this measurem
