Improving Prospects for the Direct Detection of Higgsino Dark Matter

This seminar from the NYU Physics department features Harikrishnan Ramani of the University of Delaware discussing strategies to enhance the direct detection of Higgsino dark matter. Explore the challenges and potential solutions for detecting pseudo-Dirac Higgsino, one of the few remaining electroweak WIMP candidates. Learn why the LHC cannot reach the required 1.1 TeV target mass even at full luminosity, and why indirect detection methods depend heavily on the dark matter density profile at the galactic center. Understand the "inelastic dark matter" phenomenon where direct detection is only possible when mass splitting is smaller than the initial center of mass kinetic energy. Discover innovative approaches to overcome these limitations through novel astrophysics applications, utilization of elements from the periodic table's end, and large volume neutrino detectors.
