DESCRIPTION:We have investigated effects of interaction terms on non-pertu
 rbative particle production.  It is well known that time-varying masses in
 duce abundant particle production\, such as the preheating theory.  As our
  conclusion\, it is possible to induce particle production even if the mas
 s term of a particle species is not varying in time.  Such particles are p
 roduced through the interactions with other fields\, whose mass terms are 
 varying due to a time-dependent background.  The rather general result is 
 that the amount of produced particles without time-dependent masses can be
  comparable with the particle density produced directly by the varying bac
 kground if the strength of interaction terms is reasonably large.  In this
  talk\, we will explain with a simple but illustrative model and show anal
 ytic and numerical results.\n\nhttp://indico.fuw.edu.pl/conferenceDisplay.
