Hunt for Sterile Neutrinos: Decay at Rest Experiments

In the standard model of the elementary particles, the number of neutrinoflavor is three. However, there have been indications of existence of 4th neutrino, called sterile neutrino, in some neutrino oscillationrelated experiments. A number of experiments are planned to test whether such indications are true or not. Among them, experiments which use neutrinosfrom pi+, K+, mu+ decay at rest (DAR) are promising because the energy spectra of neutrinosare very well known and clean oscillation measurements are possible. In this proceedings, properties of such DAR neutrinosand LSND, JSNS2, OscSNS and KPipe experiments are briefly introduced.
