Probe of WW production in vector boson fusion topology

Measurement of WW production rate in vector boson fusion topology is presented using the semileptonic final state from diboson decay. This analysis is a benchmark for future studies of WW scattering at high energies. The analysis is performed using a data sample corresponding to an integrated luminosity of 20/fb at 8 TeV proton-proton collision energies recorded by the CMS experiment at the Large Hadron Collider.
