Searching for Light Physics at the LHC
Abstract: Over the last years, new physics in terms of a novel weakly-interacting massive particle (WIMP) has come more and more under pressure from experimental null results. While the remaining WIMP parameter space will be probed by next generation dark matter experiments, models of light new physics have become increasingly popular over the last decade. In an effort to explore the parameter space of such light physics, a myriad of custom designed high-precision/low-energy experiments has been proposed. In this talk, however, I will argue that existing LHC multipurpose experiments like ATLAS and CMS have a so far unexploited potential to probe light physics via appearing displaced recoil jets. In the first part of the talk, I will discuss the sensitivity of this signature to (ultra-)light scalar and axionic dark matter, while in the second part I will show its sensitivity to high-energy neutrino scattering.
