Curvture Regularization and Dynamical Vacuum Structure in Pseudo-Complex General Relativity
Fridolin Weber, Peter Otto Hess, Cesar Augusto Zen Vasconcellos
Whether classical spacetime remains welldefined at arbitrarily high curvature is a central question. In general relativity, singularities signal the breakdown of the classical desc…
Neutrino oscillation in a minimal length spacetime
Luísa Nadal Camargo, Thiago Oliveira Ferreira, Dimiter Hadjimichef +1
We investigate how neutrino oscillations are modified in a non-commutative spacetime characterized by a minimal length scale, described by the Quesne-Tkachuk algebra. By incorporat…
Pseudo-Complex Gravity as a Geometric Resolution of the Black Hole Information Paradox
Fridolin Weberand Peter O. Hess, Cesar A. Zen Vasconcellos
We investigate the black hole information paradox in the setting of pseudo-complex gravity, a covariant geometric extension of general relativity that introduces a minimal length s…
Cosmic inflation in an extended non-commutative foliated quantum gravity: the wave function of the universe
César A. Zen Vasconcellos, Peter O. Hess, José de Freitas Pacheco +8
We propose a novel extension to the recently developed non-commutative Riemannian foliated branch-cut quantum gravity (BCQG). Based on an extended Faddeev-Jackiw symplectic deforma…
Effects of a Generalized Uncertainty Principle on the MIT Bag Model Equation of State
Marcelo Netz-Marzola, César Augusto Zen Vasconcellos, Dimiter Hadjimichef
The Generalized Uncertainty Principle (GUP) is motivated by the premise that spacetime fluctuations near the Planck scale impose a lower bound on the achievable resolution of dista…
On the possibility of a 130 GeV gamma-ray line from annihilating singlet fermionic dark matter
T. H. Franarin, C. A. Z. Vasconcellos, D. Hadjimichef
There is evidence for a spectral line at GeV in the Fermi-LAT data that can be explained as dark mater particles annihilating into photons. We review a well known…
Glueball-glueball potential in a constituent gluon model
M. L. L. da Silva, D. Hadjimichef, C. A. Z. Vasconcellos
In this work we use a mapping technique to derive in the context of a constituent gluon model an effective Hamiltonian that involves explicit gluon degrees of freedom. We study glu…
Glueball decay in the Fock-Tani formalism
D. T. da Silva, M. L. L. da Silva, D. Hadjimichef +1
We investigate the two-meson decay modes for . In this calculation we consider this resonance as a glueball. The Fock-Tani formalism is introduced to calculate the decay…
Glueball-glueball scattering in a constituent gluon model
M. L. L. da Silva, D. Hadjimichef, C. A. Z. Vasconcellos
In this work we use a mapping technique to derive in the context of a constituent gluon model an effective Hamiltonian that involves explicit gluon degrees of freedom. We study glu…
