Abstract:
Over several decades, the Standard Model of particle physics has demonstrated tremendous and continued success in providing testable predictions that have been confirmed experimentally. However, it has reached a stage where it is ripe for expansion or revision, as it cannot properly explain all of the major experimental data in the field, such as an explanation for the existence of dark matter in the Universe. One way to search for dark matter or new physics is at the energy frontier at the LHC, probing energies comparable to those present very shortly after the Big Bang. In this talk, I will review some recent experimental results for searches for new physics using data from the ATLAS experiment. Signs of new physics could also first show up as subtle surprises in the behavior of the known particles that could indirectly hint at new physics. I will discuss details about the detector performance, with a focus on the ATLAS inner tracker, which are crucial for such searches and precision measurements in particular. I will conclude with a discussion on recent results on dark matter and new physics using global fits.
