Constraints on Long-Ranged Interactions Between Dark Matter and the Standard Model
Zachary Bogorad, Peter Graham, Harikrishnan Ramani
Dark matter's existence is known thanks to its gravitational interaction with Standard Model particles, but it remains unknown whether this is the only force present between them.…
Highly Excited Electron Cyclotron for QCD Axion and Dark-Photon Detection
Xing Fan, Gerald Gabrielse, Peter W. Graham +3
We propose using highly excited cyclotron states of a trapped electron to detect meV axion and dark photon dark matter, marking a significant improvement over our previous proposal…
Enhancing Direct Detection of Higgsino Dark Matter
Peter W. Graham, Harikrishnan Ramani, Samuel S. Y. Wong
While much supersymmetric weakly interacting massive particle (WIMP) parameter space has been ruled out, one remaining important candidate is Higgsino dark matter. The Higgsino can…
Constraints on Dark Matter from Dynamical Heating of Stars in Ultrafaint Dwarfs. Part 2: Substructure and the Primordial Power Spectrum
Peter W. Graham, Harikrishnan Ramani
There is a large and growing interest in observations of small-scale structure in dark matter. We propose a new way to probe dark matter structures in the $\sim 10 - 10^8 \, M_\odo…
