Charting the unknown: results from recent searches for new phenomena at the LHC — •Katharina Behr — Deutsches Elektronen-Synchrotron DESY, Notkestr. 85, 22607 Hamburg

A wide variety of searches at the LHC target new particles and interactions not described in the Standard Model of Particle Physics (SM). These are postulated to address the open questions of particle physics, such as the hierarchy problem, the origin of the baryon asymmetry in the universe, or the nature of dark matter, which the SM fails to answer. In the absence of evidence for new phenomena in the data analysed to date, new analysis strategies are needed to explore previously inaccessible kinematic regimes and provide sensitivity to signatures too subtle or exotic to have been picked up by previous searches.

In this talk, I will review results of recent searches for new phenomena conducted by the ATLAS and CMS Collaborations on their full LHC Run-2 datasets, highlighting new experimental techniques that allow us to explore previously uncharted regions in the vast landscape of new signatures and models beyond the SM. I will also give a brief outlook on the potential of searches on data from the on-going LHC Run 3.
