As one of the most exciting and promising experiments for new crucial discoveries in the field of high-energy particle physics, ATLAS contributed many novel results presented in dedicated talks at the recent Rencontres de Moriond conference.

Where is all the new physics? Could it be sneaking past the standard searches? ATLAS researchers have developed innovative ways to search for new particles, improving their search programme to ensure they have the best chance of discovering new physics in Run 3 of the LHC.

The ATLAS Collaboration performed a new search for exotic Higgs-boson decays using the full dataset of 13 TeV proton-proton collisions delivered by the LHC between 2015 and 2018.

Many theories suggest that the Higgs boson discovered in 2012 by the ATLAS Experiment is but the first to be observed from a larger Higgs family. A new ATLAS analysis searches for the presence of a new singly-charged Higgs boson.

The ATLAS Collaboration announces the first observation of “tqγ production”: the associated production of a single top quark and a photon in proton-proton collisions at the LHC.

The ATLAS Collaboration has devised a range of new strategies to look for long-lived particles with various possible characteristics. Four new results from this effort were presented at the recent Lepton-Photon and La Thuile conferences.

The winter conference season is in full swing! 2022 marks the return of full auditoriums and coffee-break chats, as the La Thuile and Rencontres de Moriond conferences welcome participants to venues in the Italian Alps. These are the first large-scale, international particle physics conferences to be held in person in the COVID era – reuniting experimentalists and theorists after almost two years of virtual meetings.
