A search is presented for anomalous quartic gauge boson couplings in vector-boson scattering. The data for the analysis correspond to 20.2 fb^-1 of √(s)=8 TeV pp collisions, and were collected in 2012 by the ATLAS experiment at the Large Hadron Collider. The search looks for the production of WW or WZ boson pairs accompanied by a high-mass dijet system, with one W decaying leptonically, and a W or Z decaying hadronically. The hadronically decaying W/Z is reconstructed as either two small-radius

Constraints on the anomalous quartic gauge boson coupling parameters α_4 and α_5 are set by fitting the transverse mass of the diboson system, and the resulting 95 confidence intervals are -0.024<α_4<0.030 and -0.028<α_5<0.033.
