The Branch-cut Cosmology: A topological canonical quantum approach
Peter O. Hess, César A. Zen Vasconcellos, José de Freitas Pacheco +2
In this contribution we sketch a branch-cut quantum formulation of the Wheeler-DeWitt equation analytically continued to the complex plane. As a starting point, we base our approac…
Pushing the limits of time beyond the Big Bang singularity: Scenarios for the branch cut universe
C. A. Z. Vasconcellos, P. O. Hess, D. Hadjimichef +3
In this contribution we identify two scenarios for the evolutionary branch cut universe. In the first scenario, the universe evolves continuously from the negative complex cosmolog…
Pushing the limits of time beyond the Big Bang singularity: The branch cut universe
C. A. Z. Vasconcellos, P. O. Hess, D. Hadjimichef +3
In this article we follow a previously developed theoretical approach, based in the tools of the singular semi-Riemannian geometry, to push the limits of time beyond the primordial…
Matter-antimatter asymmetry and non-inertial effects
V. M. G. Silveira, C. A. Z. Vasconcellos, E. G. S. Luna +1
We investigate non-inertial effects on -violating processes using a model, based on the framework of quantum field theory in curved spacetimes, devised to account for the decay…
Ground Level Muon Flux Variation in a Cosmic Rays Simulation
E. G. Pereira, C. A. Z. Vasconcellos, D. Hadjimichef
The oscillatory movements of atmospheric air masses has been claimed to be the origin of the muon flux variation measured at the ground level. Using a cosmic ray toolkit (CORSIKA),…
Non-inertial effects on CP-violating systems
V. M. G. Silveira, C. A. Z. Vasconcellos, E. G. S. Luna +1
An analysis of accelerated kaon decays based on the Unruh effect shows a slight decrease in a CP-violation parameter for very high accelerations, as a consequence of the previously…
