摘要

The mass of the etau0027 meson is theoretically expected to be reduced at finite density, which indicates the existence of etau0027-nucleus bound states. To investigate these states, we perform missing-mass spectroscopy for the (p, d) reaction near the etau0027 production threshold. The overview of the experimental situation is given and the current status is discussed.
