Opening the GeV Window at the LHC

Synopsis

In this talk, I present a newly proposed search strategy for GeV-scale particles that couple predominantly to light quarks at the LHC. Such models have often been assumed to be experimentally indistinguishable from QCD jets. We demonstrate that this is not the case: these particles can be perturbatively produced at the LHC and promptly decay into only a few hadrons, giving rise to jets with anomalously low charged-track multiplicity and mass. I will also discuss possible improvements that can be made for HL-LHC
