摘要
Scientists from the Large High Altitude Air Shower Observatory(LHAASO)have presented roughly 1.5 years of observational data,calculating new constraints on the lifetime of heavy dark matter particles that have masses between 105 and 109 gigaelectron volts.The study,entitled“Constraints on heavy decaying dark matter from 570 days of LHAASO observations”,was recently published as a highlight letter in Physics Review Letter.
