Research Abstract

In order to study the structure of matters formed by quarks and its mechanism, a neutron detection system for measuring the radiative decay processes of negatively-charged hyperons has been developed. It detects neutrons emitted from hadron production reactions induced by a high-energy photon beam. Although due to the limited beam intensity and other reasons, we have not achieved the measurement of the intended reaction, the developed system enabled us to carry out variety of new measurements of hadron production reactions.
