  We have considered SU(2)xU(1) gauge field theory describing electroweak
interactions. We have demonstrated that centrifugal term in model Hamiltonian
increases the region of regular dynamics of Yang-Mills and Higgs fields system
at low densities of energy. Also we have found analytically the approximate
relation for critical density of energy of the order to chaos transition on
centrifugal constant. It is necessary to note that mentioned increase of the
region of regular dynamics has linear dependance on the value of the
centrifugal constant.
