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 2015 ...
