Chern - Simons term in the 4 - dimensional SU ( 2 ) Higgs Model
نویسندگان
چکیده
Using Seibergs definition for the geometric charge in SU(2) lattice gauge theory, we have managed to apply it also to the Chern-Simons term. We checked the periodic structure and determined the Chern-Simons density on small lattices L and L × 2, 4 with L = 4, 6, and 8 near the critical region in the SU(2) Higgs model. The data indicate that tunneling is increased at high temperature. aTalk presented by M. L. Laursen at the Symposium on Lattice Field Theory, Lattice 92, Amsterdam September 15-19, 1992.

Large-N Analysis of Three Dimensional Nonlinear Sigma Models
Non-perturbative renormalization group approach suggests that a large class of nonlinear sigma models are renormalizable in three dimensional space-time, while they are nonrenormalizable in perturbation theory. N = 2 supersymmetric nonlinear sigma models whose target spaces are Einstein-Kähler manifolds with positive scalar curvature belongs to this class. hermitian symmetric spaces, being homo...
متن کاملThe Chern-Simons Coefficient in Supersymmetric Non-Abelian Chern-Simons Higgs Theories
By taking into account the effect of the would be Chern-Simons term, we calculate the quantum correction to the Chern-Simons coefficient in supersymmetric Chern-Simons Higgs theories with matter fields in the fundamental representation of SU(n). Because of supersymmetry, the corrections in the symmetric and Higgs phases are identical. In particular, the correction is vanishing for N = 3 supersy...
متن کاملThe Non-abelian Chern-Simons Coefficient in the Higgs Phase
We calculate the one loop corrections to the Chern-Simons coefficient κ in the Higgs phase of Yang-Mills Chern-Simons Higgs theories. When the gauge group is SU(N), we show, by taking into account the effect of the would be Chern-Simons term, that the corrections are always integer multiples of 1 4π , as they should for the theories to be quantum-mechanically consistent. In particular, the corr...
متن کاملThe Chern - Simons number as an order parameter : classical sphaleron transitions for SU ( 2 ) - Higgs field theories for m H ≈ 120
The Chern-Simons number as an order parameter : classical sphaleron transitions for SU(2)-Higgs field theories for m H ≈ 120 GeV Abstract The classical transitions between topologically distinct vacua in a SU (2)–Higgs model, using a Higgs field of mass approximately 120 GeV, is examined to probe the crossover region between the symmetric and broken phase. Assuming the Higgs mass is constant, w...
متن کاملChern-simons Number Asymmetry from Cp-violation during Tachyonic Preheating∗
We consider the creation of non-zero Chern-Simons number in a model of the early Universe, where the Higgs field experiences a fast quench at the end of inflation. We perform numerical lattice simulations in the Abelian Higgs model in 1+1 dimensions and in the SU(2)-Higgs model in 3+1 dimensions with an added effective CP-violating term. We also comment on the appropriate choice of vacuum initi...
