Quantum fluctuations and instantons.

Slava Mukhanov
Ludwig Maximilians University Munich


The Coleman boundary conditions for instantons are reanalyzed by taking into account inevitable quantum fluctuations, We show that these fluctuations regularize the classical O(4) solutions which were singular before. In turn, these new solutions contribute to the false vacuum decay.
