Near threshold two meson production with the pd -> He-3 pi(+)pi(-) and pd -> (HeK+K-)-He-3 reactions

Wear threshold two meson production via the reactions pd --> He-3 pi(+)pi(-) and pd --> He-3 K+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 phi meson.
