Language Quarks

open access: yes, 2009
Este trabajo sintetiza muy brevemente los resultados de la reciente investigación acerca de la naturaleza de los rasgos y relaciones gramaticales (Sigurðsson 2004 et seq.). Mientras que la morfología opera con rasgos discretos (aunque abstractos) y valores de estos rasgos, la sintaxis construye y trabaja con relaciones.

Why is $${}^{208}_{82}\textrm{Pb}$$ 82 208 Pb the heaviest stable nuclide?

open access: yesEuropean Physical Journal C: Particles and Fields
In an effort to understand nuclei in terms of quarks we develop an effective theory to low-energy quantum chromodynamics in which a single quark contained in a nucleus is driven by a mean field due to other constituents of the nucleus.

New Bound States of Top-anti-Top Quarks and T-balls Production at Colliders (Tevatron, LHC, etc.)

open access: yes, 2008
The present talk is based on the assumption that New Bound States (NBSs) of top-anti-top quarks (named T-balls) exist in the Standard Model (SM): a) there exists the scalar 1S - bound state of 6t+6\bar t - the bound state of 6 top-quarks with their 6 ...

Differences between heavy and light quarks

open access: yes, 1997
The quark Dyson-Schwinger equation shows that there are distinct differences between light and heavy quarks. The dynamical mass function of the light quarks is characterised by a sharp increase below 1 GeV, whereas the mass function of the heavy quarks ...

Hadrons with Two Heavy Quarks

open access: yes, 1994
We review the spectroscopy and some properties of hadrons containing two charmed quarks, or more generally, two heavy quarks. This includes heavy baryons such as $(bcu)$, and possible exotic multiquark states.Comment: Talk given at the CHARM 2000 ...

Quark up e quark down

open access: yes, 2017
O objetivo deste trabalho é discutir a aplicação de um material didático (MD), com foco no ensino-aprendizagem de Radioatividade, composto por textos com atividades para resolução em lousa magnética. O MD visa incentivar a leitura, propiciar a interatividade, exercitar a construção e a análise de equações de emissões radioativas, diferenciar partículas
