The discovery of the Higgs boson has been a major breakthrough in 2012 and resulted in the award of the Nobel Prize in Physics to Francois Englert and Peter Higgs in 2013. The ATLAS collaboration has released many final measurements on the Higgs boson from the first run of the Large Hadron Collider. A newly optimized analysis in the decay to two W bosons studies the Higgs boson in two production modes: the production process where two gluons fuse to form a loop of top quarks that produce the Higgs boson (which provided most of the signal for the discovery in 2012), but also another, much rarer process where two W bosons radiate off colliding quarks and fuse together to produce a Higgs boson, called the vector boson fusion production (VBF). The signal significance in this VBF process has reached 3.2 standard deviations, qualifying for evidence for this rare process.
