| Research Abstract |
We performed to search for thermal-like radiations via event-horizons under high-acceleration fields by electromagnetic and strong interactions with electrons and partons as the probes, respectively. In parallel, we studied photon-photon interaction processes particularly in the case of the electromagnetic interaction, which may be background processes with respect to the thermal-like radiations. In the search, we confronted characteristic problems included in the experimental environment to understand the systematic uncertainty. However, we could list up what must be solved in future. As for the study of the background processes, as a byproduct, we found the proposed system includes an interesting aspect which can be sensitive to the low-mass and weakly coupling fields which are relevant for cosmology. We organized the international symposium where these relevant results were presented.
