Note on the Gauge Fixing in Gauge Theory
In the absence of Gribov complications, the modified gauge fixing in gauge theory ∫ DAμ{exp[−SYM (Aμ)− ∫ f(Aμ)dx]/ ∫ Dg exp[− ∫ f(Aμ)dx]} for example, f(Aμ) = (1/2)(Aμ) 2, is identical to the conventional Faddeev-Popov formula ∫ DAμ{δ(D δf(Aν ) δAμ )/ ∫ Dgδ(Dμ δf(A g ν ) δA g μ )} exp[−SYM (Aμ)] if one takes into account the variation of the gauge field along the entire gauge orbit. Despite of ...
متن کاملGauge Fixing of SU ( 2 ) Lattice Gauge Theory
I construct a Lattice Gauge Theory (LGT) with discrete Z2 structure group and an equivariant BRST symmetry that for gauge invariant observables is equivalent to the standard SU(2)-LGT. The measure of this Z2-LGT is invariant under all the discrete symmetries of the lattice. The SU(2) structure group of the original LGT is first reduced to an U(1) structure group by an equivariant BRST construct...

متن کاملA note on gauge fixing in Supergravity/Kac–Moody correspondences
We explain how to achieve the traceless gauge for the spatial part of the spin connection in the framework of the recently proposed correspondence between the (appropriately truncated) bosonic sectors of maximal supergravities and the ‘geodesic’ σ-model over E10/K(E10) at low levels. After making this gauge choice, the residual symmetries on both sides of this correspondence match precisely. Th...
متن کاملNote on Gauge Theory on Fuzzy Supersphere
We construct a supermatrix model whose classical background gives two-dimensional noncommutative supersphere. Quantum fluctuations around it give the supersymmetric gauge theories on the fuzzy supersphere constructed by Klimcik. This model has a parameter β which can tune masses of the particles in the model and interpolate various supersymmetric gauge theories on sphere.
