This thesis describes the performance of the common ATLAS b-tagging algorithms in the context of the dense environments that can be found in the decay of boosted top quarks into jets and addresses the problems related to such conditions. The results of these studies lead to the development of two new multivariate-analysis-based b-tagging algorithms called MVb and MVbCharm. The training of these new b-tagging algorithms is modified with respect to that of the current tools to take the conditions of boosted topologies better into account. Their performance is significantly improved relative to the standard algorithms for high pT b-jets and jets contained in dense environments. These...
