Neutral current neutrino-nucleus interactions at high energies
(2009) [Journal article]We present a QCD analysis of the neutral current (NC) neutrino-nucleus interaction at the small-x region using the color dipole formalism. This phenomenological approach is quite successful in describing experimental results ... -
Neutralization and wake effects on the Coulomb explosion of swift H2+ ions traversing thin films
(2015) [Journal article]The Coulomb explosion of small cluster beams can be used to measure the dwell time of fragments traversing amorphous films. Therefore, the thickness of thin films can be obtainedwith the so-called Coulomb depth profiling ... -
Neutral pion and η meson production at midrapidity in Pb-Pb collisions at √sNN = 2.76 TeV
(2018) [Journal article]Neutral pion and η meson production in the transverse momentum range 1 < pT < 20 GeV/c have been measured at midrapidity by the ALICE experiment at the Large Hadron Collider (LHC) in central and semicentral Pb-Pb collisions ... -
Neutral pion and η meson production in p–Pb collisions at √sNN=5.02 TeV
(2018) [Journal article]Neutral pion and η meson invariant differential yields were measured in non-single diffractive p–Pb collisions at √ sNN = 5.02 TeV with the ALICE experiment at the CERN LHC. The analysis combines results from three ... -
Neutral polyampholyte in an ionic solution
(1996) [Journal article]The behavior of a neutral polyampholyte (PA) chain with N monomers, in an ionic solution, is analyzed in the framework of the full Debye-Hückel-Bjerrum-Flory (DHBjF) theory. A PA chain, that in addition to the neutral ... -
Neutral to charged kaon yield fluctuations in Pb – Pb collisions at √sNN = 2.76 TeV
(2022) [Journal article]We present the first measurement of event-by-event fluctuations in the kaon sector in Pb – Pb collisions at √sNN = 2.76 TeV with the ALICE detector at the LHC. The robust fluctuation correlator νdyn is used to evaluate the ... -
Neutrino-driven electrostatic instabilities in a magnetized plasma
(2017) [Journal article]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) [Journal article]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) [Journal article]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 ... -
Neutrino structure functions in the QCD dipole picture
(2007) [Journal article]In this contribution we present an exploratory QCD analysis of the neutrino structure functions in charged current DIS using the color dipole formalism. The corresponding dipole cross sections are taken from recent ... -
Neutron emission in ultraperipheral Pb-Pb collisions at √sNN = 5.02 TeV
(2023) [Journal article]In ultraperipheral collisions (UPCs) of relativistic nuclei without overlap of nuclear densities, the two nuclei are excited by the Lorentz-contracted Coulomb fields of their collision partners. In these UPCs, the typical ... -
Neutron stars in a class of nonlinear relativistic models
(2001) [Journal article]In this work we introduce a class of relativistic models for nuclear matter and neutron stars which exhibits a parametrization, through mathematical constants, of the nonlinear meson-baryon couplings. For appropriate choices ... -
New approach for phylogenetic tree recovery based on genome-scale metabolic networkss
(2014) [Journal article]A wide range of applications and research has been done with genome-scale metabolic models. In this work, we describe an innovative methodology for comparing metabolic networks constructed from genome-scale metabolic models ... -
New approach for structural characterization of planar sets of nanoparticles embedded into a solid matrix
(2013) [Journal article]In this work we demonstrate that Medium Energy Ion Scattering (MEIS) measurements in combination with Transmission Electron Microscopy (TEM) or Grazing Incidence Small Angle X-Ray Scattering (GISAXS) can provide a complete ... -
A new approach for the determination of multiple cation locations and ordering, using the example of natural and heat-treated columbites
(2011) [Journal article]A new approach is proposed to determine unambiguously the location of four cations within the crystal structure of a natural AB2O6 columbite-type compound and derivatives, when submitted to order–disorder transitions caused ... -
A new block algorithm for full-rank solution of the Sylvester-observer equation
(2003) [Journal article]A new block algorithm for computing a full rank solution of the Sylvester-observer equation arising in state estimation is proposed. The major computational kernels of this algorithm are: 1) solutions of standard Sylvester ... -
A new calibration method for charm jet identification validated with proton-proton collision events at √𝒔 = 13 TeV
(2022) [Journal article]Many measurements at the LHC require efficient identification of heavy-flavour jets, i.e. jets originating from bottom (b) or charm (c) quarks. An overview of the algorithms used to identify c jets is described and a novel ... -
New cosmological constraints on f(T) gravity in light of full Planck-CMB and type Ia supernovae data
(2023) [Journal article]We investigate two new observational perspectives in the context of torsional gravitational modification of general relativity, i.e., the f(T) gravity: (i) We use Pantheon data of type Ia supernovae motivated by a time ... -
New detections of embedded clusters in the Galactic halo
(2016) [Journal article]Context. Until recently it was thought that high Galactic latitude clouds were a non-star-forming ensemble. However, in a previous study we reported the discovery of two embedded clusters (ECs) far away from the Galactic ... -
