Comparison of statistical treatments for the equation of state for core-collapse supernovae
(2009) [Artigo de periódico]Neutrinos emitted during the collapse, bounce, and subsequent explosion provide information about supernova dynamics. The neutrino spectra are determined by weak interactions with nuclei and nucleons in the inner regions ... -
Instabilities and propagation of neutrino magnetohydrodynamic waves in arbitrary direction
(2017) [Artigo de periódico]In a previous work [Haas et al., Phys. Plasmas 23, 012104 (2016)], a new model was introduced, taking into account the role of the Fermi weak force due to neutrinos coupled to magnetohydrodynamic plasmas. The resulting ... -
Neutrino-driven electrostatic instabilities in a magnetized plasma
(2017) [Artigo de periódico]The destabilizing role of neutrino beams on the Trivelpiece-Gould modes is considered, assuming electrostatic perturbations in a magnetized plasma composed by electrons in a neutralizing ionic background, coupled to a ... -
Neutrino magnetohydrodynamics
(2016) [Artigo de periódico]A new neutrino magnetohydrodynamics (NMHD) model is formulated, where the effects of the charged weak current on the electron-ion magnetohydrodynamic fluid are taken into account. The model incorporates in a systematic way ... -
Neutrino oscillations and instabilities in degenerate relativistic astrophysical plasmas
(2019) [Artigo de periódico]We set up a proposal to extend significantly recent works on neutrino-plasma interaction, allowing the possibility of deep degenerate and relativistic electrons, which are often present in compact stars such as high-density ... -
Search for heavy Majorana neutrinos in same-sign dilepton channels in proton-proton collisions at √s = 13 TeV
(2019) [Artigo de periódico]A search is performed for a heavy Majorana neutrino (N), produced in leptonic decay of a W boson propagator and decaying into a W boson and a lepton, with the CMS detector at the LHC. The signature used in this search ... -
Small-x neutrino-hadron structure functions within the QCD color dipole picture
(2007) [Artigo de periódico]We present an exploratory QCD analysis of the neutrino structure functions in charged current DIS using the color dipole formalism. The dipole cross sections are taken from recent phenomenological/theoretical studies in ... -
Ultralight energy neutrinos and nonlinear QCD dynamics
(2004) [Artigo de periódico]The ultrahigh energy neutrino-nucleon cross sections are computed taking into account different phenomenological implementations of the nonlinear QCD dynamics. Based on the color dipole framework, the results for the ...
