Observation of VBF Higgs with the ATLAS Detector

Vector Boson Fusion (VBF) is the second largest production of the Higgs and its contribution to the discovery of the Higgs is important. After the discovery of Higgs, Searching for Higgs with different production models is one of the most important topics at the LHC. ATLAS observed around 3 sigma with RUN1 data and achieves the first observation (5 sigma) mostly from Higgs decaying into two photons with RUN2 data. With the combination of gammagamma,ZZ*, WW* ,5.3σ/6.5σ (observed/expected) has been seen. It is the first the VBF Higgs process has been observed from one single channel. This talk will give a description of this observation and highlight VBF H->gamma gamma as a detail description of the analysis process.
