Abstract:
Two searches for non-resonant new physics phenomena are presented using the data collected with ATLAS in proton-proton collisions at the Large Hadron Collider. The 2012 √s = 8 TeV dataset is used to search for large extra spatial dimensions and the 2015 √ s = 13 TeV dataset is used to search for a four fermion contact interaction. These datasets correspond to 20.3 fb−1 and 3.2 fb−1, respectively. The searches are performed using events with dielectron final states, and combined with dimuon events for a dilepton result. Due to an absence of signal, 95% credibility levels are set on the parameters of interest using a Bayesian interpretation. Lower limits are set on the string scale MS for large extra spatial dimensions between 3.0 TeV and 5.0 TeV. Lower limits are set on the contact interaction scale Λ between 14.4 TeV and 25.2 TeV.
