The scattering of two massive vector bosons (VBS), V V ? V V with V = W or Z, is a key process to probe the nature of electroweak symmetry breaking. Many physics scenarios predict enhancements in VBS either from additional resonances or if the observed SM-like Higgs boson only partially unitarizes this amplitude.This seminar will present the first study sensitive to this process.  Same-electric-charge $W^{\pm}W^{\pm}jj$  diboson production using 20.3~fb$^{-1}$ of proton--proton collision data at $\sqrt{s}=8$ TeV recorded by the ATLAS detector at the Large Hadron Collider.
