Search for light dark matter with ionization signals in the PandaX-4T Experiment
read the original abstract
We report the search results of light dark matter through its interactions with shell electrons and nuclei, using the commissioning data from the PandaX-4T liquid xenon detector. Low energy events are selected to have an ionization-only signal between 60 to 200 photoelectrons, corresponding to a mean nuclear recoil energy from 0.77 to 2.54 keV and electronic recoil energy from 0.07 to 0.23 keV. With an effective exposure of 0.55 tonne$\cdot$year, we set the most stringent limits within a mass range from 40 $\rm{MeV/c^2}$ to 10 $\rm{GeV/c^2}$ for point-like dark matter-electron interaction, 100 MeV/c$^2$ to 10 GeV/c$^2$ for dark matter-electron interaction via a light mediator, and 3.2 to 4 $\rm{GeV/c^2}$ for dark matter-nucleon spin-independent interaction. For DM interaction with electrons, our limits are closing in on the parameter space predicted by the freeze-in and freeze-out mechanisms in the early Universe.

Producing the GeV Galactic Center Excess via Cosmic Ray-Dark Matter Scattering
Cosmic ray protons scattering off dark matter produce the Galactic Center gamma-ray excess through inelastic up-scattering followed by decay or direct elastic 2-to-3 photon production.

Search for sub-GeV dark particles in $\eta\to\pi^0+\rm{invisible}$ decay
No signal found in first search for eta to pi0 plus invisible dark scalar decay, setting branching fraction limits of (1.8-5.5)x10^-5 at 90% CL and improving DM-nucleon cross section bounds by ~5 orders of magnitude.

Super-Kamiokande Strongly Constrains Leptophilic Dark Matter Capture in the Sun
Super-Kamiokande data constrains the DM-electron scattering cross-section for leptophilic dark matter to ~4e-41 cm2 below 100 GeV, exceeding direct detection by over an order of magnitude.
