Exploring the properties of the pure spinor b ghost
(2014-08-07) [Tese de doutorado]
This thesis is based in part of my work during the Ph.D. and aims to present a detailed analysis of some newly studied properties of the composite non-minimal pure spinor b ghost. First, a review of the minimal and non-minimal ...
New physics from warped compact extra dimensions: from model building to colliders signals
(2014-06-03) [Tese de doutorado]
The Higgs field of the Standard Model theory for elementary particles and interactions can be realized as a composite state from an underlying strong sector. Such hypothesis is very attractive as an ultraviolet completion ...
Dynamical gluon masses in perturbative calculations at loop level: towards an effective loop expansion for quantum chromodynamics
(2014-12-16) [Tese de doutorado]
This thesis is based on part of the work done during the Ph.D., and it concerns the two distinguished domains of Quantum Chromodynamics (QCD) at zero temperature: the low-energy, confined domain, and the high-energy, ...
Quantum aspects of solitons and deformations on Ad'S IND. 4'x C'P POT.3' ('S POT. 7')
(2014-07-10) [Tese de doutorado]
In this thesis we will analyze two problems for backgrounds of the type AdS4 × M. In the ﬁrst part, we will discuss the ambiguities in the computation of the 1-loop correction for the energy of spinning strings on AdS4 ...
Aspectos quânticos e clássicos da instabilidade de campos fundamentais em espaços-tempos astrofísicos
(2014-07-28) [Tese de doutorado]
Besides serving as eﬀective models for more complex interactions, scalar ﬁelds also arise as interesting extensions of General Relativity, candidates for dark matter or key ingredients in cosmological models. Their ...
Efeitos da equação de estado em hidrodinâmica relativística através de alguns observáveis
(2014-03-31) [Tese de doutorado]
We present results of a systematic study of the role of the equation of state in the hydrodynamic model. We simulate Au+Au collisions for two energies of the Relativistic Heavy Ion Collider (RHIC), 130 and 200 GeV per ...
