Ciência e religião : possibilidades para o ensino de Física com um viés histórico e epistemológico em um contexto de introdução de Física Quântica no Ensino Médio
Hoernig, André Felipe; Massoni, Neusa Teresinha; Hadjimichef, Dimiter (2022) [Artículo de periódico]Com o presente texto trazemos alguns resultados empíricos sobre percepções de estudantes de Ensino Médio sobre a relação entre Ciência e Religião, bem como alguns indícios de viabilidade de atividades que foram conduzidas ... -
Differences between the 3P0 and C3P0 model in the charming strange sector
Silva, Daniel Tavares da; Roschildt, Nathan; Hadjimichef, Dimiter; Rodrigues, Hercules Borges (2015) [Artículo de periódico]The goal of this work is to establish a comparison between the very well studied 3P0 model and a bound-state corrected version, the C3P0 model, obtained from applying the Fock- Tani transformation to the 3P0 model, in the ... -
f0(1370) decay in the Fock-Tani formalism
Silva, Mario Luiz Lopes da; Silva, Daniel Tavares da; Vasconcellos, Cesar Augusto Zen; Hadjimichef, Dimiter (2007) [Artículo de periódico]We investigate the two-meson decay modes for f0(1370). In this calculation we consider this resonance as a glueball. The Fock-Tani formalism is introduced to calculate the decay width. -
Física quântica na escola básica : investigações para a promoção de uma aprendizagem conceitual, histórica e epistemológica
Hoernig, André Felipe; Massoni, Neusa Teresinha; Hadjimichef, Dimiter (2021) [Artículo de periódico]O presente trabalho versa sobre possibilidades, tendências da literatura e estratégias didáticas para introduzir a Física Quântica no Ensino Médio, atentando para uma aprendizagem conceitual, visando conciliar História e ... -
Matter-antimatter asymmetry and non-inertial effects
Silveira, Vinicius Medeiros Gomes da; Vasconcellos, Cesar Augusto Zen; Luna, Emerson Gustavo de Souza; Hadjimichef, Dimiter (2021) [Artículo de periódico]We investigate non-inertial effects on CP-violating processes using a model, based on the framework of quantum field theory in curved spacetimes, devised to account for the decay of accelerated particles. We show that the ... -
Nuclear densities and the statistics of nucleonic constituents
Betz, Michel Emile Marcel; Hadjimichef, Dimiter (1994) [Artículo de periódico]In the quark model of the nucleon, the Fermi statistics of the elementary constituents can in6uence significantly the properties of multinucleon bound systems. In the Skyrme model, on the other hand, the basic quanta are ... -
QCD effective charges and the structure function F2 at small-x : higher twist effects
Hadjimichef, Dimiter; Luna, Emerson Gustavo de Souza; Peláez, Marcela (2020) [Artículo de periódico]We consider the effect of higher twist operators of the Wilson operator product expansion in the structure function F2(x, Q 2) at small-x, taking into account QCD effective charges whose infrared behavior is constrained ... -
Quantum Physics teaching and the theory of Social representations : investigating the presence of quantum mysticism concepts among high school students in the south of Brazil
Hoernig, André Felipe; Massoni, Neusa Teresinha; Hadjimichef, Dimiter (2023) [Artículo de periódico]The present work deals with possibilities for contribution of the Theory of Social Representations (TSR) as a reference for group learning, with techniques and methodologies that are specific to it, to facilitate the ... -
A Wheeler–DeWitt non-commutative quantum approach to the branch-cut gravity
Bodmann, Benno August Ludwig; Hadjimichef, Dimiter; Hess, Peter Otto; Pacheco, Jose Antonio de Freitas; Weber, Fridolin; Razeira, Moises; Degrazia, Gervasio Annes; Marzola, Marcelo Netz; Vasconcellos, Cesar Augusto Zen (2023) [Artículo de periódico]In this contribution, motivated by the quest to understand cosmic acceleration, based on the theory of Hoˇrava–Lifshitz and on the branch-cut gravitation, we investigate the effects of non-commutativity of a mini-superspace ... -
A Wheeler–DeWitt quantum approach to the branch-cut gravitation with ordering parameters
Bodmann, Benno August Ludwig; Vasconcellos, Cesar Augusto Zen; Hess, Peter Otto; Pacheco, Jose Antonio de Freitas; Hadjimichef, Dimiter; Razeira, Moises; Degrazia, Gervasio Annes (2023) [Artículo 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 ...
