Future electron beam dump experiments

Abstract: A beam dump experiment can be seamlessly added to the proposed International Linear Collider (ILC) program because the high-energy electron beam should be dumped after the collision point. The ILC beam dump experiment will provide an excellent opportunity to search for new long-lived particles(LLP). An LPP couple to a photon, such as axion-like particles, can be searched there. Furthermore, the photon and electron in EM shower hit nuclei and produce hadrons. As a motivated physics case, we study the projected sensitivity of heavy neutral leptons at the ILC beam dump experiment. The study shows,somewhat counter-intuitively, that the reach would be significantly extended in mass and coupling, even compared with the other proposed searches.　I also introduce proposed ALP studies using KEK linac; currently, test beam studies are starting.
