Abstract
We consider tunneling processes in QFT induced by collisions of
elementary particles. We propose a semiclassical method for estimating
the probability of these processes in the limit of very high
collision energy. As an illustration, we evaluate the maximum
probability of induced tunneling between
different vacua in a (1+1)-dimensional scalar model with boundary
interaction.
