A Beauty-ful Boson: Search for the Higgs Boson Produced in Association with a Vector Boson and Decaying into a Pair of b-quarks Using Large-R Jets with the ATLAS Detector

The analysis described in this thesis is the search for the Higgs boson, decaying into bb pair, in the associated production with a vector boson, in the extreme Higgs boson transverse momentum region where the Higgs boson is reconstructed using the large-R jet technique. The use of the large-R jets allows to add a part of the phase space unexplored so far, which is particularly sensitive to possible new physics.

The analysed data have been collected at LHC by the ATLAS detector between 20...
