For this reason, present searches target the so-called ‘VH production’ mode, in which the Higgs boson is produced in association with a heavy vector boson, V, namely a W or a Z boson, identified via its leptonic decay. WebThis collision is a typical example of the vector-boson-fusion mode of Higgs production, which creates additional jets along the LHC beam (dark yellow cones). Studying the production of two Higgs bosons is the most obvious way to understand the field responsible for the Higgs boson.
