27. Near or Far Detectors? Optimizing Long-Lived Particle Searches at Electron-Positron Colliders

In this talk, I will explore the discovery potential for long-lived particles at the 250-GeV ILC. I will discuss possible gains of a dedicated far detector over the main detector for sub-GeV axion-like particles a, produced via e+ e− → aγ or e+ e− → Zγ → (aγ)γ and decaying into pairs of charged leptons. Our conclusions can also help optimizing long-lived particle searches at the FCC-ee and...

We study capability of the ILC beam dump experiment to search for dark matter particles, comparing the performance of the electron and positron beam dumps. The dark matter particles involving the dark photon are considered as benchmark models, where electron recoil processes and decays of heavier dark matter particles are included as signal events.
We find that the ILC beam dump experiment...

26. Observing Axion Emission from Supernova with Collider Detectors

We consider a possibility to observe the axion emission from a nearby supernova (SN) in the future, which can be known in advance by the pre-SN alert system, by collider detectors like the LHC detectors (i.e., the ATLAS and the CMS) and the ILC detectors (i.e., the ILD and SiD). The axion from the SN can be converted to the photon by the strong magnetic field in the detector and the photon...
