Low-scale inflation in a model of dark energy and dark matter
P. Q. Hung, Eduard Masso, Gabriel Zsembinszki
We present a complete particle physics model that explains three major problems of modern cosmology: inflation, dark matter and dark energy, and also gives a mechanism for leptogen…
Imprint of spatial curvature on inflation power spectrum
Eduard Masso, Subhendra Mohanty, Akhilesh Nautiyal +1
If the universe had a large curvature before inflation there is a deviation from the scale invariant perturbations of the inflaton at the beginning of inflation. This may have some…
Unified Model for Inflation and Dark Energy with Planck-Scale Pseudo-Goldstone Bosons
Eduard Masso, Gabriel Zsembinszki
We present a model with a complex and a real scalar fields and a potential whose symmetry is explicitly broken by Planck-scale physics. For exponentially small breaking, the model…
Scalar Field Oscillations Contributing to Dark Energy
Eduard Masso, Francesc Rota, Gabriel Zsembinszki
We use action-angle variables to describe the basic physics of coherent scalar field oscillations in the expanding universe. These analytical mechanics methods have some advantages…
On the Gravitational Field of Antimatter
Eduard Masso, Francesc Rota
The gravitational field of matter and that of antimatter could differ. This might be one signature of quantum gravity. We show that primordial Big Bang Nucleosynthesis restricts su…
Primordial Helium Production in a Charged Universe
Eduard Masso, Francesc Rota
We use the constraints arising from primordial nucleosynthesis to bound a putative electric charge density of the universe. We find , four ord…
