Gravitational corrections to the Einstein-Scalar-QCD model
Huan Souza, L. Ibiapina Bevilaqua, A. C. Lehum
This study employs the effective field theory approach to quantum gravity to investigate a non-Abelian gauge theory involving scalar particles coupled to gravity. The study demonst…
Gravitational corrections to a non-Abelian gauge theory
Huan Souza, L. Ibiapina Bevilaqua, A. C. Lehum
This paper is part of a series of papers exploring the renormalization of field theories coupled to gravity using the effective field theory framework. In previous works we studied…

In this paper we discuss the universality of the renormalization of the gauge coupling constant in the quantum electrodynamics coupled to the Einstein's gravity in the framework of…
Gravitational corrections to two-loop beta function in quantum electrodynamics
L. Ibiapina Bevilaqua, M. Dias, A. C. Lehum +3
In this work, we use the framework of effective field theory to couple Einstein's gravity to quantum electrodynamics (QED) and determine the gravitational corrections to the two-lo…
Renormalization group improvement of the effective potential in six dimensions
Huan Souza, L. Ibiapina Bevilaqua, A. C. Lehum
Using the renormalization group improvement technique, we study the effective potential of a model consisting of scalar fields transforming in the fundamental representat…
Soft supersymmetry breaking in the nonlinear sigma model
L. Ibiapina Bevilaqua, A. C. Lehum, A. J. da Silva
In this work we discuss the dynamical generation of mass in a deformed supersymmetric nonlinear sigma model in a two-dimensional () space-time. We introduce the…

In this work we study the three-dimensional supersymmetric Chern-Simons-matter model in a noncommutative space-time. We construct the action of the noncommutative $U(N…
On semiclassical analysis of pure spinor superstring in an AdS_5 x S^5 background
Yuri Aisaka, L. Ibiapina Bevilaqua, Brenno C. Vallilo
Relation between semiclassical analyses of Green-Schwarz and pure spinor formalisms in an AdS_5 x S^5 background is clarified. It is shown that the two formalisms have identical se…
Notes on beta-deformations of the pure spinor superstring in AdS(5) x S(5)
Oscar A. Bedoya, L. Ibiapina Beviláqua, Andrei Mikhailov +1
We study the properties of the vertex operator for the beta-deformation of the superstring in AdS(5) x S(5) in the pure spinor formalism. We discuss the action of supersymmetry on…
