The Large Hadron Collider at CERN has provided us with an unprecedented number of proton collisions at unprecedented energies. One of the main motivations of the LHC was the discovery of the Higgs boson, which was achieved in 2012. Now over a decade later, this begs the question: what have we been doing at the LHC since the discovery of the Higgs boson? Together, we will explore the richness...
The ATLAS detector at Large Hadron Collider (LHC) at CERN has collected $140~\mathrm{fb}^{-1}$ of proton-proton collisions over the course of the 2015-2018 data-taking period, allowing for some of the most stringent tests of the Standard Model of particle physics and new measurements of its parameters with unprecedented accuracy. This presentation details the first observation of the...
Many extensions to the Standard Model (SM) predict the existence of strongly interacting dark sectors, which behave similarly to Quantum Chromodynamics (QCD) but interact weakly with SM particles. Depending on the parameters of the dark sector, one potential LLP signature could be that of an "emerging jet" – a spray of particle tracks after proton-proton collision dominantly composed of...
The Large Hadron Collider (LHC) at the Conseil Européen pour la Recherche Nucléaire (CERN) features a 27km ring of superconducting magnets that accelerate protons into extremely high-energy collisions to probe for new physics. Found along the ring is ATLAS (A Toroidal LHC ApparatuS), a cylindrical multi-purpose detector with various subsystems. At the heart of the detector, the electromagnetic...
A search for a novel experimental collider signature called 'Emerging Jets' is presented using the ATLAS experiment at the Large Hadron Collider. This signature is based on a model of 'Dark-QCD' wherein dark quarks will shower and hadronize analogous to quantum chromodynamics (QCD) in the Standard Model (SM). If produced in particle collisions, these dark particles would form dark-jets:...
