Dark Matter Particle Explorer. Credit: DAMPE Collaboration Dark Matter Particle Explorer (DAMPE) Collaboration directly observed a spectral softening of helium nuclei at about 34TeV for the first time. This work was based on measurements data of the helium spectrum with kinetic energies from 70 GeV to 80 TeV (17.5 GeV/n […]
