On the capture rates of big bang neutrinos by nuclei within the Dirac and Majorana hypotheses
(IOP Publishing, 2018-10)
The capture rates of non-relativistic neutrinos on beta decaying nuclei depends on whether their mass is Dirac or Majorana. It is known that for relic neutrinos from the big-bang, and within minimal assumptions, the rate ...
Calculation of primordial abundances of light nuclei including a heavy sterile neutrino
(IOP Publishing, 2015-08)
We include the coupling of a heavy sterile neutrino with active neutrinos in the calculation of primordial abundances of light-nuclei. We calculate neutrino distribution functions and primordial abundances, as functions ...
Complementarity of eastern and western hemisphere long-baseline neutrino oscillation experiments
(2003-01-01)
We present a general formalism for extracting information on the fundamental parameters associated with neutrino masses and mixings from two or more long baseline neutrino oscillation experiments. This formalism is then ...
On the energy of the protons producing the very high-energy astrophysical neutrinos
(IOP Publishing, 2021-03)
We study the distribution of the energy of the protons that can produce an astrophysical neutrino with a given observed energy, in the TeV-PeV range, both through pp or pγ interactions. Due to the increasing multiplicity ...
Constraints on neutrino masses from a Galactic supernova neutrino signal at present and future detectors
(North-HollandGrupo de Fisica y Astrofisica Computacional (FACOM), 2017)
Fenomenologia do Mecanismo Seesaw Tipo-I
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM FÍSICA, 2020-05-22)
Neutrinos are elementary particles present on many phenomena in nature, from nuclear physics,
such as the beta decay, to cosmology, where neutrinos have an essential role in the evolution of
the universe. In the Standard ...
