Gauge-invariant signatures of spontaneous gauge symmetry breaking by the Hosotani mechanism / Akerlund, Oscar ; de Forcrand, Philippe
The Hosotani mechanism claims to achieve gauge-symmetry breaking, for instance $SU(3) \to SU(2)\times U(1)$. [...]

On jet substructure methods for signal jets / Dasgupta, Mrinal ; Powling, Alexander ; Siodmok, Andrzej
We carry out simple analytical calculations and Monte Carlo studies to better understand the impact of QCD radiation on some well-known jet substructure methods for jets arising from the decay of boosted Higgs bosons. [...]

Emerging Jets / Schwaller, Pedro (CERN) ; Stolarski, Daniel (CERN) ; Weiler, Andreas (CERN ; DESY)
In this work, we propose a novel search strategy for new physics at the LHC that utilizes calorimeter jets that (i) are composed dominantly of displaced tracks and (ii) have many different vertices within the jet cone. [...]
