The galaxy halo formation rate
Published 1998“…The rate at which galaxy halos form is thought to play a key role in explaining many observable cosmological phenomena such as the initial epoch at which luminous matter forms and the distribution of active galaxies. …”

Neutrino CP violation and sign of baryon asymmetry in the minimal seesaw model
Published 2018-03-01“…The sign of the CP violating Dirac phase at low energy is fixed by the observed cosmological baryon asymmetry since there is only one phase parameter in the model. …”

Relaxation of Higgs mass and cosmological constant with four-form fluxes and reheating
Published 2020-01-01“…The Higgs mass parameter can be relaxed to a correct value due to the four-form coupling to the Higgs field and it stops changing due to an extremely suppressed transition probability from the observed cosmological constant to AdS space. We first introduce a non-minimal four-form coupling to gravity and discuss the role of a new scalar field as the inflaton and the conditions for a successful reheating at the end of relaxation.…”

On the Apparent Discretization of Spacetime and Its Connection with the Cosmological Constant
Published 2024-03-01“…The obtained result is used to infer the value of zero-point energy in the universe, which is found to be in good agreement with the observed cosmological constant. This potentially offers some hints towards the resolution of the cosmological constant problem.…”

Braneworld black holes and entropy bounds
Published 2018-01-01“…This difference is interpreted as the extra loss of information, associated to the extra dimension, when an extra-dimensional black hole is moved outward the observer's cosmological horizon. Also, it is discussed that N-bound entropy is hold for the possible solutions here. …”

Loop quantum gravity and cosmological constant
Published 2021-12-01“…Remarkably, by suitably choosing the value of the regularization parameter, the observational cosmological constant can emerge at large volume limit from the effect of quantum gravity, and the effective Newtonian constant satisfies the experimental restrictions in the meantime.…”

Effects of Scattering of Radiation on Wormholes
Published 2018-02-01“…Significant progress in the development of observational techniques gives us the hope to directly observe cosmological wormholes. We have collected basic effects produced by the scattering of radiation on wormholes, which can be used in observations. …”

The cosmological dark sector as a scalar σ-meson field
Published 2018-03-01“…Abstract Previous quantum field estimations of the QCD vacuum in the expanding space-time lead to a dark energy component scaling linearly with the Hubble parameter, which gives the correct figure for the observed cosmological term. Here we show that this behaviour also appears at the classical level, as a result of the chiral symmetry breaking in a low energy, effective $$\sigma $$ σ -model. …”

Axiogenesis with a heavy QCD axion
Published 2022-10-01“…Abstract We demonstrate that the observed cosmological excess of matter over anti-matter may originate from a heavy QCD axion that solves the strong CP problem but has a mass much larger than that given by the Standard Model QCD strong dynamics. …”
