Probing sterile neutrino dark matter in the PTOLEMY-like experiment

Ki-Young Choi, Erdenebulgan Lkhagvadorj, Seong Moon Yoo

We study the prospect to detect the cosmic background of sterile neutrinos in the Tritium $\beta$-decay, such as PTOLEMY-like experiments. The sterile neutrino with mass between 1 eV -…
