Structure functions of the 2 d O ( n ) non - linear sigma models
We investigate structure functions in the 2–dimensional (asymptotically free) non– linear O(n) σ–models using the non–perturbative S–matrix bootstrap program. In particular the exact small (Bjorken) x behavior is derived. Structure functions in the special case of the n = 3 model are accurately computed over the whole x range for −q2/M2 < 105, and some moments are compared with results from ren...

15 صفحه اولTwisting gauged non-linear sigma-models
We consider gauged sigma-models from a Riemann surface into a Kähler and hamiltonian G-manifold X. The supersymmetric N = 2 theory can always be twisted to produce a gauged A-model. This model localizes to the moduli space of solutions of the vortex equations and computes the Hamiltonian Gromov-Witten invariants. When the target is equivariantly Calabi-Yau, i.e. when its first G-equivariant Che...
متن کاملNoncommutative Linear Sigma Models
We examine noncommutative linear sigma models with U (N) global symmetry groups at the one-loop quantum level, and contrast the results with our previous study of the noncommutative O(N) linear sigma models where we have shown that Nambu-Goldstone symmetry realization is inconsistent with continuum renormaliza-tion. Specifically we find no violation of Goldstone's theorem at one-loop for the U ...
متن کاملCurrent Algebra of Classical Non-Linear Sigma Models
The current algebra of classical non-linear sigma models on arbitrary Riemannian manifolds is analyzed. It is found that introducing, in addition to the Noether current jμ associated with the global symmetry of the theory, a composite scalar field j, the algebra closes under Poisson brackets.
