Event Details

During the LHC Run-I, the ATLAS collaboration conducted an extensive research program to search for physics beyond the standard model (BSM), pursuing both model dependent and independent approaches. Supersymmetry (SUSY) is one of the most appealing BSM models, predicting unique new physics signatures at the LHC. The model independent approach is normally based on rigorous tests of standard model (SM) predictions. In this talk, Dr. Nguyen will present the search for strongly produced squarks and gluinos in the jet plus missing transverse momentum channel and the dedicated search for third generation SUSY partners in the three lepton plus multiple jets channel at ATLAS. New physics searches based on tests of SM predictions are demonstrated through the measurement of the Wγγ triboson cross section, which is sensitive to the quartic gauge couplings between W bosons and gammas. An effective field theory framework is used to describe the new physics signatures from the anomalous quartic gauge couplings. Finally, the ATLAS tile calorimeter, one of the key detector systems behind the above measurements, is discussed.
