Perturbative Solution to D-terms in N=2 Models and Metrics
نویسنده
چکیده
N = 2 gauged non-linear sigma models are examined classically and their D-terms are solved. The variation of the classical Lagrangian in order to solve for the auxiliary fields is identical to integrating these modes functionally. The latter is performed for the general quotient. The D-term solution is equivalent to solving, a coupled set of algebraic equations.

We consider four-parameter D = 4, N = 2 string models with Hodge numbers (4, 214 − 12n) and (4, 148), and we express their perturbative Wilsonian gravitational coupling F1 in terms of Siegel modular forms.
متن کاملBi-objective optimization of multi-server intermodal hub-location-allocation problem in congested systems: modeling and solution
A new multi-objective intermodal hub-location-allocation problem is modeled in this paper in which both the origin and the destination hub facilities are modeled as an M/M/m queuing system. The problem is being formulated as a constrained bi-objective optimization model to minimize the total costs as well as minimizing the total system time. A small-size problem is solved on the GAMS software t...
متن کاملSemiclassical models for uniform-density Cosmic Strings and Relativistic Stars
In this paper we show how quantum corrections, although perturbatively small, may play an important role in the analysis of the existence of some classical models. This, in fact, appears to be the case of static, uniform– density models of the interior metric of cosmic strings and neutron stars. We consider the fourth order semiclassical equations and first look for perturbative solutions in th...
متن کاملPerturbative formalism of Lovelock gravity
In this work we develop a perturbative formalism for the treatment of Lovelock theories of gravity. We consider in detail D-dimensional models in Lovelock gravity with an induced metric given by the product of the metrics of two maximally symmetric spaces. We first explicitly obtain the Lovelock action, Hamiltonian constraint, gravitational momenta, and dynamical equations for this type of mini...
متن کاملExact Hypermultiplet Dynamics in Four Dimensions
The hypermultiplet low-energy effective action (LEEA) in N=2 supersymmetric four-dimensional (4d) gauge theories can receive both perturbative (at one loop) and non-perturbative (due to instantons) quantum corrections. The manifestly N=2 supersymmetric Feynman rules in harmonic (twistor) superspace are used to calculate the perturbative hypermultiplet LEEA that results in the Taub-NUT non-linea...
