Near threshold two meson production with the pd→3Heπ+π− and pd→3HeK+K− reactions

Near threshold two meson production via the reactions pd→3Heπ+π− and pd→3HeK+K− was measured kinematically complete with the MOMO experiment at COSY. The obtained two pion invariant mass spectra and angular distributions depict a remarkable deviation from phase space. The two kaon data are consistent with phase space topped by a clear signal of the φ meson.
