A Time Projection Chamber, called as “HypTPC”, is the central tracker of Hyperon Spectrometer (HS). The HypTPC measures the trajectory of charged particles in three dimension with high precision of about 300 µm. We can achieve a good momentum resolution of \(\Delta p/p \sim 2.4\)% for proton and 1.4% for \(\pi ^{ \pm }\) in \(\sigma \). The HypTPC has a large acceptance because an experimental target will be installed inside the TPC volume. By using this powerful detector, we propose three experiments at J-PARC to search for the new hadronic states. The E42 experiment aims to search for H-dibaryon, which is composed of uuddss quarks with (isospin) I = (spin) J = 0. The E45 is baryon spectroscopy experiment and we can confirm the N^* and \(\Delta ^{*}\) baryons. The E72 experiment searches for a narrow \(\Lambda \) resonance using \(p(K^{ - },\eta )\) reaction. The HypTPC will open up the new possibility of hadron physics.
