| Abstract: | The two-loop expression for the vacuum energy density in a constant magnetic field is obtained on the basis of the chiral perturbation theory. The dependence of the quark and gluon condensates on the field intensity H is found. Pis’ma Zh. éksp. Teor. Fiz. 70, No. 11, 711–717 (10 December 1999) |
