QCD Sum Rules for the X(3872) as a mixed molecule-charmoniun state
R. D. Matheus, F. S. Navarra, M. Nielsen +1
We use QCD sum rules to test the nature of the meson X(3872), assumed to be a mixture between charmonium and exotic molecular [c\bar{q}][q\bar{c}] states with J^{PC}=1^{++}. We fin…
The small behavior of the gluon structure function from total cross sections
E. G. S. Luna, A. A. Natale, C. M. Zanetti
Within a QCD-based eikonal model with a dynamical infrared gluon mass scale we discuss how the small behavior of the gluon distribution function at moderate is directly…
Elastic scattering and the proton form factor
F. Carvalho, A. A. Natale, C. M. Zanetti
We compute the differential and the total cross sections for scattering using the QCD pomeron model proposed by Landshoff and Nachtmann. This model is quite dependent on the e…
Inflationary and dark energy regimes in 2+1 dimensions
M. H. Christmann, F. P. Devecchi, G. M. Kremer +1
In this work we investigate the behavior of three-dimensional (3D) cosmological models. The simulation of inflationary and dark-energy-dominated eras are among the possible results…
Transition from accelerated to decelerated regimes in JT and CGHS cosmologies
M. H. Christmann, F. P. Devecchi, G. M. Kremer +1
In this work we discuss the possibility of positive-acceleration regimes, and their transition to decelerated regimes, in two-dimensional (2D) cosmological models. We use general r…
