Abstract: This thesis presents a search for vector boson fusion production of
Higgs bosons in the H->WW->lnulnu channel using the 20fb^-1 2012 ATLAS data set. The
analysis uses support vector machines in order to distinguish signal and background events.
First, an analysis is performed using a 2-class support vector machine, designed to
separate signal events from all backgrounds. In addition, ... read morea 3-class support vector machine
analysis is performed in which back- ground events are separated into two classes. The
results of both the 2 and 3-class analyses are consistent with the findings of other ATLAS
analyses and with Standard Model predictions to within 1 sigma.
