Abstract
The possible existence of phenomena beyond the standard model of particle physics at the TeV scale implies the production of highly boosted heavy objects, whose decay products tend to be collimated and can be reconstructed as jets with large radius parameter. Jet substructure analysis techniques have been developed and successfully applied to LHC Run1 data to perform cross section measurements in the high transverse momentum regime and searches for new physics phenomena. An overview of selected physics results obtained by ATLAS and CMS using jet substructure techniques is presented.
Highlights
An impressive quantity of results have been obtained by the experiments at the Large Hadron Collider (LHC) in the last few years
These results confirm the validity of the Standard Model (SM) of particle physics at an unprecedented energy scale, and complete the SM picture with the observation of its last missing piece, the Higgs boson
Several models of beyond-the-SM (BSM) physics have been proposed and searches for BSM physics at the LHC have reached the TeV scale. At this energy scale SM massive particles are produced with a large Lorentz boost, their subsequent decay products tend to be highly collimated and can partially overlap in the reconstruction phase in case of final states characterized by the presence of several jets, like the hadronic decays W/Z/H → qqor t → bqq 1 (Fig. 1)

Several models of beyond-the-SM (BSM) physics have been proposed and searches for BSM physics at the LHC have reached the TeV scale At this energy scale SM massive particles (vector bosons W, Z, top quark t, and the Higgs boson H) are produced with a large Lorentz boost, their subsequent decay products tend to be highly collimated and can partially overlap in the reconstruction phase in case of final states characterized by the presence of several jets, like the hadronic decays W/Z/H → qqor t → bqq 1 (Fig. 1).
