Book Description
A search for a heavy new particle Y decaying to a Standard Model Higgs boson H and another new particle X is presented. The search is performed using 139 fb−1 of p−p collision data at √s = 13 TeV recorded by the ATLAS detector. The H boson is identified through its decays to bb, with the only assumption applied to X being that it decays hadronically. The X is identified through a novel anomaly detection method via the use of a Variational Recurrent Neural Network trained directly on data collected by the ATLAS detector. This effort marks the first application of a fully unsupervised machine learning method to an ATLAS analysis. An additional benchmark based on interpreting the Y → XH process in the context of a heavy vector triplet model in which the X decays to two quarks defines an additional signal region in which upper limits on the HVT process cross section are reported at 95% confidence level.

Book Description
This thesis presents a search for resonances in diboson production in the [llqq] final state using Lint = 20.3 fb --1 of proton-proton collision data collected at a center of mass energy of 8 TeV with the ATLAS detector. No significant excess over the Standard Model expectation is observed. Consequently 95% confidence level upper limits are set on the cross section times branching fraction for the production of bulk Randall-Sundrum gravitons and extended gauge model W' bosons, leading to the exclusion of masses below 740 GeV and 1590 GeV, respectively.
