Abstract
Studies of highly-boosted top quarks produced inclusively in pp collisions at √ s = 14 TeV are discussed. Using Monte Carlo models after a fast detector simulation, it is shown that jet masses alone provide a sensitive probe for top quarks produced inside highp T jets. The hadronic decays of such top quarks can be studied in a data-driven approach by analysing shapes of jet-mass distributions. It is shown that inclusive production of boosted top quarks can be observed if it has a cross section at least twice larger than the prediction from the approximate next-to-next-to-leading-order (aNNLO) calculation for the t t¯ process. The t t¯ process with the nominal aNNLO strength can be measured using the masses of jets after a b-tagging.
