   Is there a name for the QFT with two real fields. \psi and \phi, and   
   interaction   
      
        g \psi^2 \phi^2,   
      
   where obviously g should be positive and both fields are Klein-Gordon   
   fields which may or may not have mass. The descriptive name in the title   
   could of course be used, but is this system known under a special name?   
      
   (I'm interested since it looks like the simplest example of two   
   interacting fields and perhaps the wave functional of its solutions   
   could be visualized..)
