Electric-magnetic duality in N = 2 supersymmetric gauge theory
(Universidade Estadual Paulista (Unesp), 2015-09-04)
In this dissertation we present a description of the electric-magnetic duality and their classical and quantum aspects. Our analysis starts from the suggested magnetic monopoles by Dirac in 1931 [1] and goes until the work ...
A simpler prescription to calculate MHV amplitudes for gravitons at tree level in superstring theory
(Universidade Estadual Paulista (Unesp), 2013-08-23)
In this work we review the simple formulas found for MHV amplitudes of gluons and gravitons inside the contexts of super-Yang-Mills with supersymmetry N = 4 and supergravity with supersymmetry N = 8. We then review the ...
Quantização de partículas com spin
(Universidade Estadual Paulista (Unesp), 2007-03-12)
Aclassical relativistic particleis described by means of Dirac's formalism for constrained systems, where the constraints come from the reparametrization invariance required by an explicitly covariant theory. We introduce ...
