Experimental results in the boosted regime

An overview of analyses using data at $\sqrt{s}$ = 7 TeV and 8 TeV of proton-proton collisions at the LHC is presented. These analyses use boosted techniques to search for new phenomena involving top quarks and to measure the production of top quarks at high transverse momenta. Such techniques involve top-quark tagging algorithms, boson-tagging algorithms, and strategies for b-tagging and lepton identi cation in the environment where the top quark decay products are close to each other. The strategies are optimized for the di fferent final states and for di fferent ranges of the transverse momenta of the particles involved, improving on traditional resolved analysis strategies.
