Estratégias para o ensino da Teoria da relatividade no Ensino Médio : uma análise da produção acadêmica
(2023) [Artigo de periódico]Este artigo apresenta uma análise da produção acadêmica em nível de Mestrado Nacional Profissional em Ensino de Física no intuito de responder à seguinte questão: Quais são as estratégias mais utilizadas para o ensino da ... -
A Monte Carlo Method for calculating Lynden-Bell equilibrium in self-gravitating systems
(2023) [Artigo de periódico]We present a Monte Carlo approach that allows us to easily implement Lynden-Bell (LB) entropy maximization for an arbitrary initial particle distribution. The direct maximization of LB entropy for an arbitrary initial ... -
Por uma educação científica mais reflexiva e humanista : a contribuição da visão crítica da ciência de Sandra Harding
(2024) [Artigo de periódico]Este texto objetiva apresentar uma síntese das ideias principais da epistemologia feminista crítica da ciência de Sandra Harding, com vistas a aproximar essas ideias da educação científica para a formação de cidadãos mais ... -
Search for direct production of GeV-scale resonances decaying to a pair of muons in proton-proton collisions at √s = 13 TeV
(2023) [Artigo de periódico]A search for direct production of low-mass dimuon resonances is performed using √ s = 13 TeV proton-proton collision data collected by the CMS experiment during the 2017–2018 operation of the CERN LHC with an integrated ... -
First measurement of prompt and non-prompt D∗+ vector meson spin alignment in pp collisions at √s = 13 TeV
(2023) [Artigo de periódico]This letter reports the first measurement of spin alignment, with respect to the helicity axis, for D∗+ vector mesons and their charge conjugates from charm-quark hadronisation (prompt) and from beauty meson decays ... -
Performance of the local reconstruction algorithms for the CMS hadron calorimeter with Run 2 data
(2023) [Artigo de periódico]A description is presented of the algorithms used to reconstruct energy deposited in the CMS hadron calorimeter during Run 2 (2015–2018) of the LHC. During Run 2, the characteristic bunch-crossing spacing for proton-proton ... -
The impact of environmental effects on active galactic nuclei : a decline in the incidence of ionized outflows
(2023) [Artigo de periódico]Active galactic nuclei (AGNs) have generally been considered to be less frequent in denser environments due to a lower number of galaxy-galaxy interactions and/or the removal of their gas-rich reservoirs by the dense ... -
Measurement of non-prompt D0-meson elliptic flow in Pb–Pb collisions at √sNN = 5.02 TeV
(2023) [Artigo de periódico]t The elliptic flow (v2) of D0 mesons from beautyhadron decays (non-prompt D0) was measured in midcentral (30–50%) Pb–Pb collisions at a centre-of-mass energy per nucleon pair √sNN = 5.02 TeV with the ALICE detector at the ... -
Measurement of the low-energy antitriton inelastic cross section
(2024) [Artigo de periódico]In this Letter, the first measurement of the inelastic cross section for antitriton–nucleus interactions is reported, covering the momentum range of 0.8 ≤ 𝑝 < 2.4 GeV∕𝑐. The measurement is carried out using data recorded ... -
Modulation of ionic conduction using polarizable surfaces
(2023) [Artigo de periódico]Hybrid ionic-electronic conductors have the potential to generate memory effects and neuronal behavior. The functionality of these mixed materials depends on ion motion through thin polarizable channels. Here, we explore ...
