Nucleon Form Factors of the Isovector Axial - Vector Current
The theoretical and experimental status of the isovector axial-vector current form factors GA(q 2) and GP (q 2) of the nucleon is reviewed. We also describe a new calculation of these form factors in manifestly Lorentz-invariant chiral perturbation theory (ChPT) with the inclusion of axial-vector mesons as explicit degrees of freedom.
متن کاملAbelian current algebra and the Virasoro algebra on the lattice
We describe how a natural lattice analogue of the abelian current algebra combined with free discrete time dynamics gives rise to the lattice Virasoro algebra and corresponding hierarchy of conservation laws.
متن کاملCurrent Algebra on the Torus
We derive the N-point one-loop correlation functions for the currents of an arbitrary affine Kac-Moody algebra. The one-loop amplitudes, which are elliptic functions defined on the torus Riemann surface, are specified by group invariant tensors and certain constant taudependent functions. We compute the elliptic functions via a generating function, and explicitly construct the invariant tensor ...
متن کاملCURRENT ALGEBRA AND GAUGE THE ORlE
The methods of current algebra are applied to the problem of calculating corrections to the symmetries of the strong interactions in renormalixable gauge theories of the weak and electromagnetic interactions. The strong interactions are described by a neutral-vector-gluon model, so that their symmetries are just the symmetries of the quark mass matrix, and are determined by the vacuum expectati...
متن کاملBosonization and Current Algebra of Spinning Strings
We write down a general geometric action principle for spinning strings in d-dimensional Minkowski space, which is formulated without the use of Grassmann coordinates. Instead, it is constructed in terms of the pull-back of a left invariant Maurer-Cartan form on the ddimensional Poincaré group to the world sheet. The system contains some interesting special cases. Among them are the Nambu strin...
