Energy dependence of coherent photonuclear production of J/ψ mesons in ultra-peripheral Pb-Pb collisions at √sNN = 5.02 TeV
(2023) [Artigo de periódico]The cross section for coherent photonuclear production of J/ψ is presented as a function of the electromagnetic dissociation (EMD) of Pb. The measurement is performed with the ALICE detector in ultra-peripheral Pb-Pb ... -
The dangerous link between coal dust exposure and DNA damage : unraveling the role of some of the chemical agents and oxidative stress
(2023) [Artigo de periódico]Exposure to coal mining dust poses a substantial health hazard to individuals due to the complex mixture of components released during the extraction process. This study aimed to assess the oxidative potential of residual ... -
Search for Z′ bosons decaying to pairs of heavy Majorana neutrinos in proton-proton collisions at √s = 13 TeV
(2023) [Artigo de periódico]A search for the production of pairs of heavy Majorana neutrinos (Nℓ ) from the decays of Z′ bosons is performed using the CMS detector at the LHC. The data were collected in proton-proton collisions at a center-of-mass ... -
A educação profissional e tecnológica e a aprendizagem baseada em problemas no ensino híbrido e a distância: uma revisão sistemática
(2022) [Artigo de periódico]As Tecnologias Digitais de Informação e Comunicação (TDIC) têm opor-tunizado melhorias e aumento na oferta de Educação a Distância (EaD). A Aprendizagem Baseada em Problemas (PBL) vem se mostrando efetiva, principalmente ... -
Measurement of the non-prompt D-meson fraction as a function of multiplicity in proton-proton collisions at √s = 13 TeV
(2023) [Artigo de periódico]The fractions of non-prompt (i.e. originating from beauty-hadron decays) D0 and D+ mesons with respect to the inclusive yield are measured as a function of the charged-particle multiplicity in proton-proton collisions at ... -
A Wheeler–DeWitt quantum approach to the branch-cut gravitation with ordering parameters
(2023) [Artigo de periódico]In this contribution to the Festschrift for Prof. Remo Ruffini, we investigate a formulation of quantum gravity using the Hořava–Lifshitz theory of gravity, which is General Relativity augmented by counter-terms to render ... -
A decade of near-infrared variability in NGC4388 : insights into the AGN structure
(2023) [Artigo de periódico]Variability studies have proven to be a powerful diagnostic tool for understanding the physics and properties of active galactic nuclei (AGNs). They provide insightsinto the spatial and temporal distribution of the emitting ... -
Desenvolvimento de um repositório de objetos de aprendizagem utilizando bancos de dados NoSQL
(2013) [Artigo de periódico]Os mecanismos de busca dos Repositórios de Objetos de Aprendizagem (ROA) são os principais meios que os usuários utilizam para localizar e obter recursos. Porém, quando se deseja localizar objetos pelos seus conteúdos, os ... -
Designing an optimal kilonova search using DECam for gravitational-wave events
(2024) [Artigo de periódico]We address the problem of optimally identifying all kilonovae detected via gravitational-wave emission in the upcoming LIGO/Virgo/KAGRA observing run, O4, which is expected to be sensitive to a factor of ~7 more binary ... -
The origin of massive compact galaxies : lessons from IllustrisTNG
(2023) [Artigo de periódico]We investigate the formation and evolution of z = 0 massive compact galaxies (MCGs) in the IllustrisTNG cosmological simulation. We found that, as in observations, MCGs are mainly old (median age ∼10.8 Gyr), have supersolar ...
