Abstract
The behavior of the vacuum in quantum chromodynamics is investigated by calculating quantum fluctuations of the gluon field in general constant background fields. One-loop contributions to the effective action result in a positive-definite imaginary part, indicating instability of the vacuum for all values of background electric- and magnetic-type field strengths.
