Detection of Light Dark Matter With Optical Phonons in Polar Materials
Simon Knapen, Tongyan Lin, Matt Pyle +1
We show that polar materials are excellent targets for direct detection of sub-GeV dark matter due to the presence of gapped optical phonons as well as acoustic phonons with high s…
Light Dark Matter: Models and Constraints
Simon Knapen, Tongyan Lin, Kathryn M. Zurek
We study the direct detection prospects for a representative set of simplified models of sub-GeV dark matter (DM), accounting for existing terrestrial, astrophysical and cosmologic…
LHC limits on axion-like particles from heavy-ion collisions
Simon Knapen, Tongyan Lin, Hou Keong Lou +1
In these proceedings we use recent LHC heavy-ion data to set a limit on axion-like particles coupling to electromagnetism with mass in the range 10-100 GeV. We recast ATLAS data as…
Searching for Long-lived Particles: A Compact Detector for Exotics at LHCb
Vladimir V. Gligorov, Simon Knapen, Michele Papucci +1
We advocate for the construction of a new detector element at the LHCb experiment, designed to search for displaced decays of beyond standard model long-lived particles, taking adv…
Tracking down Quirks at the Large Hadron Collider
Simon Knapen, Hou Keong Lou, Michele Papucci +1
Non-helical tracks are the smoking gun signature of charged and/or colored quirks, which are pairs of particles bound by a new, long-range confining force. We propose a method to e…
