Quantum-chromodynamic vacuum as a glueball condensate
Author
Summary, in English
It is argued semiquantitatively that the magnetic instability of the perturbative QCD vacuum leads to the formation of a Bose-Einstein condensate that locally can be described as a JPC=0++ gluon color-singlet bound state of "glueball." We also indicate how this result might be obtained by a more rigorous field-theoretical treatment. A general discussion of the global properties of the "glueball vacuum" is given, and as an illustration of our ideas we construct a phenomenological model in which the bag constant is related to the QCD scale .
