In addition to the dominant decay mode to ${{\mathit D}}{{\overline{\mathit D}}}$ , ${{\mathit \psi}{(3770)}}$ was found to decay into the final states containing the ${{\mathit J / \psi}}$ (BAI 2005 , ADAM 2006 ). ADAMS 2006 and HUANG 2006A searched for various decay modes with light hadrons and found a statistically significant signal for the decay to ${{\mathit \phi}}{{\mathit \eta}}$ only (ADAMS 2006 ).
