DESCRIPTION:We have investigated effects of interaction terms on non-pertu
 rbative particle production. It is well known that time-varying masses ind
 uce abundant particle production\, such as the preheating theory. As our c
 onclusion\, it is possible to induce particle production even if the mass 
 term of a particle species is not varying in time. Such particles are prod
 uced through the interactions with other fields\, whose mass terms are var
 ying due to a time-dependent background. The rather general result is that
  the amount of produced particles without time-dependent masses can be com
 parable with the particle density produced directly by the varying backgro
 und if the strength of interaction terms is reasonably large. In this talk
 \, we will explain with a simple but illustrative model and show analytic 
 and numerical results.\n\nhttp://indico.fuw.edu.pl/conferenceDisplay.py?co
