Superconformal Symmetry in Four Dimensions
We investigate the nonlinear realization of spontaneously broken N = 2 superconformal symmetry in 4 dimensions. We particularly study NambuGoldstone degrees of freedom for the partial breaking of N = 2 superconformal symmetry down to N = 1 super-Poincaré symmetry, where we get the chiral NG multiplet of dilaton and the vector NG multiplet of NG fermion of broken Q-supersymmetry. Evaluating the ...
متن کاملSuperconformal Symmetry in Four-dimensions
The N = 1, d = 4 superconformal group is studied and its representations are discussed. Under superconformal transformations, left invariant derivatives and some class of superfields, including supercurrents, are shown to follow these representations. In other words, these superfields are quasi-primary by analogy with two dimensional conformal field theory. Based on these results, we find the g...
متن کاملChiral Gauge Theory in Four Dimensions
A formulation of abelian and non-abelian chiral gauge theories is presented together with arguments for the unitarity and renormalisability in four dimensions.
متن کاملChiral Symmetry Breaking in 2 + 1 dimensions due to Sphalerons
In 2 + 1 dimensional gauge thories with SU(Nc) color and 2Nf flavors of quarks in the fundamental representation, sphalerons, if present may lead to quark condensation and chiral symmetry breaking. The effect is similar to instanton induced chiral symmetry breaking in 3 + 1 dimensions and is due to the interaction of quark propagators with sphalerons. The existence of sphalerons requires that c...
متن کاملGeometric Mechanics and Symmetry . From Finite to Infinite Dimensions
The purpose of the book is to provide the unifying viewpoint of Lagrangian and Hamiltonian mechanics in the coordinate-free language of differential geometry in the spirit of the Marsden-Ratiu school. The book is similar in content although less formal to the book by J. Marsden and T. Ratiu [7]. One can also mention the companion two-volumes book by Holm [4, 5] written at a more basic level, an...
