DM: Lab-based Searches
- Christopher Verhaaren (University of California, Irvine)
The proposed LUXE experiment at the DESY aims to probe QED at the nonperturbative regime in collisions between high-intensity laser pulses and high-energy electron or photon beams. This setup also provides a unique opportunity to search for physics beyond the standard model. In this talk we show that by leveraging the large photon flux generated at LUXE, one can probe axion-like-particles...
A rich physics program remains unexplored in the far-forward region at the LHC. The Forward Physics Facility (FPF) is a proposal to enlarge an existing cavern in the far-forward region of ATLAS to house a suite of experiments with groundbreaking new capabilities for neutrinos, long-lived particle searches, milli-charged particle searches, QCD, dark matter, dark sectors, and cosmic rays. The...
New light particles may be produced in large numbers in the far-forward region at the LHC and then decay to dark matter, which can be detected through its scattering in far-forward experiments. In the talk, we will discuss the discovery potential of such far-forward searches for light dark matter scattering off electrons or nuclei in an emulsion or liquid argon detector placed on the beam...
Paleo-Detectors are natural minerals which record damage tracks from nuclear recoils over geological timescales. Minerals commonly found on Earth are as old as a billion years, and modern microscopy techniques may allow to reconstruct damage tracks with nanometer scale spatial resolution. Thus, paleo-detectors would constitute a technique to achieve keV recoil energy threshold with exposures...
Accelerator-based searches for dark matter provide a unique opportunity to expand the search for particle dark matter to the sub-GeV mass regime. In this region, there are exciting opportunities to search for dark sector signatures, mediators and the dark matter itself, that are unconstrained. DarkQuest is a proton fixed-target experiment that would use a high-intensity beam of 120 GeV protons...
Higgsinos are a particularly compelling form of dark matter, and are on the verge of detection by multiple current experimental avenues. They can arise in models with decoupled scalars that enjoy the benefits of depending on very few parameters while still explaining gauge coupling unification, dark matter, and most of the hierarchy between the Planck and electroweak scales, and they remain...
